Blue Whale The Biggest Animal in World

Blue whale classification

Blue whales are marine mammals including the genus Balaenoptera in Balaenoptiidae family. Is the scientific name Balaenoptera musculus. There are three recognized subspecies of Balaenoptera musculus. Named Balaenoptera musculus musculus subspecies found in the north Atlantic and the north Pacific Ocean. Subspecies named Balaenoptera musculus intermedia is not native to the southern part of the world. The third species, Balaenoptera musculus brevicauda often referred to as the Little Blue Whale and live in the Indian Ocean and in the southern part of the South Pacific. If you read the texts of the older of the blue whale you might find a fourth subspecies, indica Balaenoptera musculus. Today, the most powerful Blue whales do not agree however that the whale Balaenoptera musculus brevicauda subspecies belonging.

Blue whales name

Blue whales are known by several different common names in addition to blue whales, such as the Great Blue Whale, Sibbald's Rorqual, Rorqual Great Northern and sulfur-bottom whale. The second part of the scientific name of Blue whale, musculus, can be defined as the "muscle" and "little mouse" in Latin. Blue Whale was named by Carl Linnaeus academic year 1785.

Blue whales food type

Blue whales feed primarily on krill, but studies have shown that sometimes may also swallow small fish, squid and animals that accidentally caught during a blue whales filter krill. Krill are small marine crustaceans, such as shrimp and zooplankton form. All sequences belonging to various species of Krill and krill Euphausiacea therefore sometimes referred to as Euphausiids.

Blue whales feed on a variety of different species of krill. The blue whales that live in the North Pacific will eat a lot of Euphausia pacficia example, Nyctiphanes symplex, Thysanoessa inermis, Thysanoessa longipes and Thysanoessa spinifera. A blue whales live in the North Atlantic but will feed mainly on Meganyctiphanes norvegica, Thysanoessa inermis, Thysanoessa longicaudata and Thysanoessa raschii. Blue whales inhabit the cold Antarctic waters known to have Euphausia crystallorophias, Euphausia Superba and Euphausia vallentni as their main food source.

Blue whales feeding

Blue whales feed by taking a large amount of water into its mouth and squeezing it out through the baleen plate  it mentioned that act as filters. Water is forced out of the mouth of a blue whale ventral bag and tongue. The krill is too large to pass through the plate Baleen and be swallowed by a blue whale as soon as the water has been squeezed out of his mouth.

Blue whales are always trying to find dense krill concentrations likely to receive adequate amounts of nutrients. Therefore they would normally spend their days at depths below 100 meters and feed near the surface during the night. A blue whale feeding dives are more likely to last between 10 and 20 minutes. The longest recorded dive is 36 minutes long.

Humpback Whale The Whalebone Whales Animal

Humpback whale classification

Humpback whales are marine mammals in Megaptera Balaenoptiidae genus and family. Megaptera novaeangliae scientific name is and that is one of the Baleen whale mentioned in Mysticeti subordo. Pope Baleen also known as whale bone whales or great whales, and differentiate yourself from the Cetacea subordo toothed whale with plates Baleen not have teeth. Baleen pancakes used to filter water.

Humpback whale ranges

Humpback whales inhabit all oceans of the world, from the Antarctic ice edge to about 65 ° N latitude. They do not live in the Baltic Sea, the Mediterranean or the Arctic Ocean. During the summer, you will find Humpbacks in cold water is located at high latitudes. They migrate to the waters of the tropical and sub-tropical that can mate and have their calves. Hump ​​back whales are mammals beruaya and annual visits to 16.000 miles (25.000 kilometers) are common. Population of the Arabian Sea but did not migrate, it remains in warm water 12 months of the year.

Humpback whale description

Humback whale body is not as thin and slender as other rorqual body, but still quite effective. Stock tail (base) narrow and slender. If you watch the whales from above, the head broad and knowledgeable, but if you even watch the whales from the side looks pretty slim. Humpbacks have 20-35 ventral groove, which extends slightly beyond the center. Slouching top of the head and also because the lower jaw bump sporting shaped buttons. This button contains one or a few stiff hair. We do not yet know for sure why the buttons and hair development, but they may give humpback whale with tactile senses. They may be similar to cat whiskers.

Humpback whale food

Humpback whales feed during the whole summer and take place on their energy available during the winter. They are skilled predators and take a wide choice of different victims, from tiny krill to herring, capelin, sand lance and large schools of fish.

Humpback whales catch prey with a direct attack, but also common for whales to stun prey by hitting the water around the prey with a powerful worm and / or fins. Humpbacks group is also known to work together in the so-called "bubble netting fish". During the bubble net fishing, Humpbacks make a bubble tube large enough to trap air around the school of fish.

Humpback whale watching

Humpbacks tend being very inquisitive and they will often approach boats and live in a small distance from them. This naturally big loss for humpback whale population during the 20th century when they were hunted as a whole from the ship, but only a few countries currently involved in the hunt humpback whale. Curiosity humpback whales today make popular pets among whale watchers. You can take part in a whale traveling in different parts of the world, including Byron Bay north of Sydney, the Bay of Biscay west France, western peninsula Snæfellsnes Iceland, Newfoundland coast and Vancouver in Canada and along the St. Lawrence River north .. In the United States, watch Humpback whales occur along the sides of the Atlantic and Pacific coast. You can for example get a whale boat in Washington, New England, Alaska and Hawaii

Great White Shark The Amazing Water Predator

The Great White Shark is macropredator found especially in temperate seas and oceans, but the Great White Shark may also be occasional tropical waters. This is especially an inmate epipelagic, meaning that it can usually be found in the upper layer of the ocean, usually between the sea surface and the thermocline at a depth of about 200 meters. The Great White Shark is known However bold sometimes well below 250 meters. It can be found in the waters serfline and very far from the beach. The Great White Shark is available from offshore islands where the water is deep and shallow beach located close to each other, and offshore reef fish can be found.

Great White Shark is actually not just white. Above, their color varies from almost black to gray while the ventral surface is white or whitish. Hip fins can be seen with olive and gray. In strong sunlight, lateral surface can display almost bronze colored sheen. The area surrounding the gill-slit and on the basis of fins often blotched. The same thing happened with the small, dark spots or dark irregular on the sides of the posterior to the fifth gill slit. Every Great White Shark has a individual coloring and patterns, but there are also similarities district. For example, the Great White Shark off Cape Province in South Africa generally show more olive tones, while the Great White Sharks off California in the U.S. has coloring very dark gray. Great White sharks in the Mediterranean Sea are usually olive-brown or gray.

There's always a lot of speculation about the maximum size of the Great White Shark. Unconfirmed sources claim that large female White Shark over 7 meters look out Kangarro Island in Australia in 1987. In the same year, shark female from Malta reported as 713 centimeters. In October 1998, a picture of this yet examined sharks and shark turned out to be more than 530 centimeters. Most experts believe that the maximum length of the Great White Shark is somewhere around 6 meters. The smallest adult Great White Sharks found in the wild is around 120 centimeters. We still do not know for certain length at maturity for the Great White Shark, and it is possible that different populations reach maturity at different lengths. But we know that the female Great White Shark often mature when they are between 450 and 500 centimeters, and that male Great White Shark often mature when they are around 350 centimeters. A study on the Great White Shark 21 show that they mature when they are around 10-12 years, but this is just an individual study on quite a few individuals and can not be used to make general assumptions.

The Great White Shark has a conical nozzle, with a somewhat blunt. Large teeth, shaped like a triangle and rough-sawn placed in patterns like. Their Latin name, Carcharodon carcharias, actually means "jagged-toothed One '. The Great White Shark is equipped with five large gill opening. The first dorsal fin is almost an equilateral triangle, with somewhat concave rear margin. In very young individuals, the first dorsal fin rounded at the apex, and grew pointier during the first two years. The second dorsal fin is always very small at the Great White Shark. Crescent-shaped tail fin, and the Great White Shark is greater than 2.0 meters usually have acute end point. In the newborn sharks, the lower surface of the tail is generally more compressed and round. This area but will grow rapidly after birth and will look like the surface of the tail of a large adult White Shark.

The Great White Shark Carcharodon genus belonging and close relative called four other mackerel sharks in the family Lamnidae. Most historians agree that when Aristotle and other Greek writers write about "the Lamia scary monster" they refer to the animals we now call the Great White Shark. Lamia and Lamie name is still used in some Mediterranean language, such as Greek and the language of southern France. During the 16th century naturalist Guillaume Rondelet suggest that perhaps the prophet Jonah in the Bible is not swallowed by the whale, but the Great White Shark. Just like today, the Great White Shark is well feared and admired, and surrounded by a lot of rumors. Historically, the Great White Shark has been known by several different names. There is always only one who recognized white shark species, but has been mentioned Squalus carcharias, Lamia carcharias, Verus carcharias, Carcharodon rondeletii, and Squalus carcharias Carcharodon smithii. Currently, formal latin name Carcharodon carcharias, which means A jagged-toothed.

Detailed knowledge about the reproductive habits of the Great White Shark rare, but at least increased rapidly over the last few years. Previously, most of the ideas and know about Great White Shark breeding is based on a comparison with other related species of shark that is known to the scientific community. There is a report from 1937 on the arrest of pregnant shark three years earlier, but was not sure if this is the Great White Shark or some other species. It was not until the 1980's that a more detailed study of the Great White Shark pregnancy occurs. Confirmed reports speak about 5 to 10 embryos, but there are also unconfirmed reports that around 14 embryos. Yu girls develop placenta is not available, and even embryos preserved by unfertilised egg consumption (oophagy). Embryos also swallow their own teeth warehouse, presumably to return to the calcium and other minerals, but is yet to be confirmed. Time of pregnancy is unknown, but is estimated at around 12 months. Birth may occur in temperate shelf waters from spring to late summer. A Great White Shark newborn is between 120 and 150 centimeters.

The actual coitus not witnessed, but the surface of the curious behavior performed by Great White Shark that may be part of the mating ritual has been observed. Mating rituals of other species of sharks often include biting and gripping with the teeth, and the bite mark was found on the pectoral fins, hips, and dorsum of the female Great White Shark which shows that this may be part of their mating ritual as well. Large adult Great White Sharks of both sexes and their offspring have been seen together in certain areas around the world, which may mean that the district nursing policy for the Great White Shark. Examples of such areas are the waters around Japan, South and East Australia, New Zeeland, South Africa's Eastern Cape Province, Southern California and Baha in the U.S. and South-Central Mediterranean Sea (especially between Tunisia and Western Sicily). Great White Shark was a little older, but still less than a year old, was arrested outside Algeria, North Aegean and France in the Mediterranean.

Blue shark is one of the fastest animal

Blue shark, Prionace glauca, easy to distinguish from other sharks in blue staining. Carcharhinidae this family owned, which means that it is a Requiem shark. When you watch the blue shark from the top you will see indigo blue color, while blue sharks observed from the side looks bright blue. White belly and tip of pectoral and anal fins have a dark color. Body elongated and slender blue sharks are usually able to achieve a measure 3.8 meters (13 feet), but the longest blue shark ever found even greater than that, and measured 400 cm. Blue sharks heaviest known weight is 205.9 kg. Very long pectoral fins of blue sharks always have the same size with the length of gill opening date and nozzle tip sharks. Snout long and has a conical shape. Upper lobe of caudal fin blue shark is far greater than the lower, and base of the tail has a weak keel. There is no line in between. All blue sharks have big eyes covered by a nictitating membrane.

Teeth in the upper and lower jaw that is equipped with a valve triangle or smooth jagged edges smooth. Serrated teeth for catching blue sharks facilitate smooth animals, such as squid. Teeth located in the line, and new teeth will smoothly rotate into place immediately after the old tooth was tired, lost or damaged. Blue Shark will only use the first two rows of teeth when hunting, other line only to play into place when needed.

Blue Shark is one of the fastest swimming shark, and can easily keep speed with the most fish species. Body long, slender and perfect for swimming fast as water-resistant to be very small. Large tail fin moving side to side and give a lot of strength for blue sharks. This swim with a sleek and powerful enough to make the leap out of the water. Further study is needed to confirm the maximum speed blue sharks. Some scientists estimate that the maximum speed to about 35 km / hour (22 miles per hour), while others claim that the maximum speed can be as much as 97 km / h (60 miles per hour).

The Blue Shark is found in most of the world, between 50 º and 50 º latitude LU S in offshore waters and coastal waters. It inhabits the Atlantic and Pacific Ocean and the Indian Ocean and liked both temperate and tropical waters. It is believed to be from the widest ranging chondrichthyian and is highly migratory. A blue shark off the coast of New Zealand tagged then found 1,200 miles off the coast of Chile. The Atlantic Blue shark follow warm Gulf Stream and traveled across the Atlantic each year. Their journey starts in the Caribbean Sea and the proceeds along the east coast and then to Europe. They then turned to the south and follow the coastline of West Africa before they turn south west and swim back to the Caribbean sea.

In the West you can see the Atlantic blue sharks from Newfoundland in Canada and down to Argentina. It is also found in the Middle Atlantic and from Norway to South Africa in the Eastern Atlantic. (The Mediterranean included.) In the Indo-West Pacific is spread from East Africa to Malaysia and Japan. It is often seen throughout Australia, New Zealand and New Caledonia. Eastern Pacific blue sharks inhabit the vast territory between the Gulf of Alaska and Chile.

Blue sharks are especially seafood, but also often found near coastal waters, especially where narrow continental landing. In temperate climates blue sharks will often stay close to the water surface in the pelagic region. In the warm tropical waters to dive deeper, because prefer water temperatures between 7 º and 16 º C are usually found further down. Blue sharks known depth range is from 0 to 350 meters, and generally found up to 150 m. Blue sharks will often form large schools. These schools are often composed of men only or women only, and all blue sharks are the same size. We still do not know why they do this, but maybe a way to prevent the attack from larger predators.

A blue shark bait especially in squid and bony fish. Pelagic fish usually formed the basis of Blue shark diet, such as swordfish, tuna, mackerel, cod, herring, and sea raven. Seal, flatfish, and pelagic red crab carcasses Cetacea also part of the normal diet. Blue sharks will often attack fish that are caught by long lines or similar capture tool, which unfortunately means that blue sharks often entangled in the equipment itself. Blue sharks are also known to occasionally eat seabirds and garbage.

Blue shark is believed to be one of the most breeding species of large sharks, but minimum population doubling time is more than 14 years. Viviporous breeding methods, which means that the eggs that develop into puppies in female blue sharks and receive nutrients in the body. After mating with a Blue Shark female can store sperm for several months, sometimes even years. The sperm covered in his oviducal gland where they will be given nutrients to stay alive. When he finally ovulates, fertilization occurs and Blue shark pups born alive after a period of 9 to 12 months of pregnancy term. One liter of blue sharks usually contains 25-50 puppies, large litters but as 135 have been reported. The larger the female blue shark, dog children more in each litter. Very small blue sharks can have litters with no more than 4 birds. A baby blue sharks dog is between 40 and 51 cm (16 inches and 20) long. A female blue sharks will not become sexually mature until it has grown to be at least 2.2 to 3.2 meters (7-11 feet), while the male blue sharks usually due at the time was between 1.8 and 2 , 8 meters (6 and 9 feet). Blue shark exceeds the maximum age of 20 years.

Blue shark always should be treated with caution as there have been reported attacks on humans. Blue shark hunted and sold as food. Meat sold fresh or preserved, and popular fin soup. Hiding from the Blue Shark applied to the skin. Blue sharks are classified as low risk / near threatened with extinction.

Tiger Sharks Are Intelligent Spotted Animals

The Tiger Shark Tiger Shark called as black, tiger-like markings. Latin name is Galeocerdo Cuvier and belongs to the family Carcharhinidae. Famous signs found in the back of the gray-brown of the Tiger Shark, while the belly is off-white. Young Tiger Shark display a sign to see, places to grow together and form lines as Tiger Shark maturity. The Tiger Shark comes with a specific type of gill opening (spirakel) located behind the eyes of a shark. This gill opening brings direct oxygen flow to the eye and brain. One of the other interesting features in Tiger Shark body is electro-receptors that allow for Shark Tiger felt the electric current in the water. In addition, Tiger Shark has a high sense of smell and excellent eyesight. This combination makes the Tiger Shark incredible predators. A Tiger Shark can be up to 20 feet (6 meters), but the average size is 10 feet (3 meters). He was big and thick, with a blunt nose. The Tiger Shark caudal fin long and somewhat pointed, and there are hills donation to bee seen along the back of the Tiger Shark, between the two dorsal fins. The second dorsal fin is much shorter than the first. Teeth of the Tiger Shark is very jagged, like sawn edges. They are also sharp and curved, and situated in the four lines that will rotate into use as needed. The Tiger Shark will use the first two rows of teeth to catch its prey. When Tiger Shark looses or toothache, or when the teeth become worn out from frequent use, the teeth just be replaced with new ones that rotate into place for long. In Tiger Shark, teeth are the same in the upper and lower jaw.

The Tiger Shark will use the teeth to grab whatever was able to catch him alive. This opportunistic and usually make a very different diet, which includes prey such as fish, mammals, sea birds, reptiles, crabs, lobster, clams, squid, octopus, turtles and even other sharks. Part of the whales, and dolphins have also been found in the belly of the Tiger Shark. Many people are afraid of Tiger Shark, but even if it's true that Tiger Shark attack has occurred, the person is not sought and hunted as prey by Tiger Shark. Eating habits of Tiger Shark has been the focus of scientific research for many years and is well known compared to many other shark species. The Tiger Shark has earned a reputation for a tendency to incorporate elements that are very prevalent in his diet. While studying entrails Hiu Macan, scientists have found things very surprising, including ladies pajamas, rubber tires, smashing of chicken wire, tar paper, bad potatoes, some shoes, a dog, a can of Spam, cloth, bottle, and sack coal. As mentioned above, the Tiger Shark is very opportunistic and will gladly change from hunter to scavenger whenever possible. Tiger Shark while studying occupying an area is offal from slaughterhouses was removed, scientists find parts of a horse, cow and goat in stomach Hiu Macan. A Tiger Shark caught from Durban in South Africa contained the head and forequarters of a crocodile. The Tiger Shark shark considered a relatively sluggish, and the frequency of certain types of food ends up in the belly of the Tiger Shark depending on how much effort the Tiger Shark will have to use to get them. Scientists learn outside Hawaii Shark Tiger Shark Tiger found that tend to eat different things for different stages of life. Tiger sharks off Hawaii turns smallest nocturnal and feed mainly from the bottom. Their diet consists mainly of bony fish, squid, crustaceans, birds and land mammals. Tiger shark bigger on the other hand, feeding mainly on eight types of victims. Just like Tiger Shark smaller, large sharks eat all kinds of prey five mentioned above, but they also include many marine mammals, turtles and elasmobranches in their diet. The increase in size, or increased hunting efficiency, making dietary changes possible. This is common in many other shark species as well. Sometimes it could be a result of changes in the geographic region as the shark grows older.

Tiger sharks are usually found from the surface down to 1,200 feet (340 meters). They live close to the shoreline, as well as in open water. The Tiger Shark inhabit tropical and subtropical coastal waters around the world, and is also available in certain temperate waters. In the North Atlantic, the Tiger Shark is often found along the outside coast of Florida, but they can migrate north as far as Nova Scotia in Canada during their seasonal migration. Tiger sharks are also known for their long journey across the North Atlantic, and Tiger Sharks sometimes travel from the North Atlantic and all the way to South America and Africa. Tiger shark apparently prefer coastal environment, but spent quite a lot of time in the pelagic region far from the beach and during certain stages of their lives. Research shows that small Tiger Sharks live in areas other larger Tiger Shark, which likely means to avoid fights and predasi. Tiger sharks will eat the other if different Tiger Sharks.

A basic nursing for Tiger Sharks have been found in the landing outside the continental U.S. District southeast elongated estimates from outside Augusta in Georgia out of Daytona in Florida. Land nursing reaching down to about 55 fathom. There is also a Tiger Shark nursing land located off the coast of North Carolina. Tiger sharks are solitary animals and only come together to breed. Studies on Tiger Sharks in the Northwest Atlantic showed that their maturity at around 8.5 'FL, which shows maturity around the age of 7 years. This is the case for Tiger Shark men or for women. The girls because it will reach 20 to 25 percent of their maximum age when they become adults, and will have time to reproduce at least 10 times before reaching the maximum age. They have a two-year reproductive cycle. Unlike the other members of the family Carcharhinidae, Tiger Shark Ovoviviparous. This is sometimes also called viviparity aplacental. Embryo to hatch from eggs in the parent body and develop in the womb, but they will not receive any nutrition from the mother through the placenta or similar. The Tiger Shark usually produce 35 to 55 embryos, which is quite a lot for the animals Ovoviviparous. There are reports of up to 82 embryos Tiger Shark in a liter. Time for Tiger Sharks pregnancy has not been confirmed, and some sources claim 9 months while others believe that the pregnancy is more than one year. Female will give birth during late spring or early summer. Tiger Shark newborn is 20-30 inches (51-76 centimeters)

English Mastiif The Giant Dog

Origin

The English Mastiff was probably brought to England before the time of Christ. It was used by the Romans as a gladiator dog and pitted against bears, bison and other dogs. History as the domestic dog as a companion guardian, guards and sheep.

Scorpion The Exotic Animal

There are around 2000 different species of scorpions. They are found in most of the southern region around 49 ° N except Antarctica and New Zeeland. They can accept a variety of desert summer temperatures well below zero. Several genera of scorpions (ex. Euscorpius, bothriurid,) can survive-25C. All know species of predatory arthropods, not insects, and have eight legs. All species of scorpions of neon and glow under UV light.

Scorpions active at night and spend most of the day hiding in the cool pores in basements or under a rock and hit a tree trunk. They avoid the light at anytime they can. They come out at night to hunt insects, small arthropod and small reptiles. They hunt to catch their pray with their pinchers called chelae. Some prey species from destroying more poisonous varieties while others inject their prey with venom neurotoxin presented by stinger at the tip of the tail. This poison will kill or paralyze prey so the scorpion can eat it. They may just like a spider's only liquid food.

Natural predators include birds scorpions, centipedes, lizards, mice, possums, and rats.

Scorpions have a body divided into two segments of the cephalothorax (also called the prosoma) and abdomen (opisthosoma).

Cephalothorax is also called the prosoma. A more common name for the cephalothorax is to simply call the head of a scorpion. This is the part that contains the carapace, eyes, chelicerae (mouth parts), pedipalpus (claws) and four pairs of walking legs.

The opisthosoma or abdomen consists of two distinct parts, mesosoma and metasoma (tail scorpion). Mesosoma is the front of the stomach and consists of six segments. The first segment of the mesosoma, the front half of the stomach, consisting of six segments. First two segments are segments of my most important to mention first segment contains the sexual organs as well as a complementary pair of vestigial and modified form structures called genital operculum. The second segment bears a pair of sensory organs known as pectines featherlike, final four segments each contain a pair of book lungs. All segments plated.

Metasoma, more popularly known as the tail also contains six segments. The latter of which contains the stinger of a scorpion (Telson) and anus of a scorpion. The teslon / stinger containing venom glands contained in vesicles and stinger itself, aculeus syringes.

Tarantula Spider One Venomous Animals

Tarantula spider belongs to the family Theraphosidae. Most of the big and hairy species but there are smaller species as well. There are about 900 species of tarantulas and tarantulas are found across the world, from the tropical environment to the desert. Some arboreal species while others live and hunt on the ground. The name originally referred to a tarantula spider wolf Europe only and can be traced to the Italian city of Taranto. The name was then used for all spiders Theraphosids when Europe began to explore areas that have a lot of big spiders, such as America.

Tarantula is a particularly predatory attack other insects, but larger species will also eat small reptiles, amphibians, rodents and birds that have resulted in their being referred to as the bird spider. Venomous tarantulas and use poison to kill their prey. But most of the species are harmless to humans. The most dangerous species produce toxins that will cause extreme discomfort, sometimes lasting for days, but the bite will not kill humans unless an allergic reaction occurs. No deaths have been associated with a tarantula spider. Although they do not spin nets for hunting, all species of tarantulas can produce silk every sleep many species in silk tents, while others use silk to reinforce the walls in their pores. They can also use silk to help them climb.

Tarantula has anatomy similar to other spiders and you can read more about the anatomy of spiders by visiting our spider parts.

Some tarantula species show sexual dimorfisme, males are usually smaller and have a dull coloration than females. Males in some species have hooks tibialis used to hold the female while mating. Tarantula teen sex can be determined by the fact that male tarantulas have cast exuvium to fusillae exiandrous or spermathecae while women do not. It is also possible to do this but the ventral sexing less reliable, especially because it is hard to do what is right.

Male tarantulas have a shorter life span than women, and many who died soon after due date, something that happened on 2-10 years depending on the species. Tarantula females can live up to 30-40 years when kept in good condition in captivity. The oldest tarantula live to 49 years. This age may be very rare in the wild because predasi. There are many animals that eat tarantulas, including parasitic wasp, tarantula hawks, which lay their eggs in and let a tarantula spider become a food source for the larvae.

In the pet trade, women are more sought after and therefore quite often more expensive. This is especially due to the fact that they live longer. Tarantula most wild caught adult male who may not be long left to live. This male-female ratio skew due to the fact that men roam around more while women living in and close their pores. Men are more likely to end up in the hands of a tarantula catcher.

Tarantula reproduce through internal fertilization. Male insert his pedipalpus to opithosoma female spiders, the opening in the lower abdomen. Get male semen into her pedipals to release semen into the web it was spinning on the ground and then put in a small pond pedipalpus semen. The pedipalpus absorb the semen and keep it up to the right of a woman to be found. Men should leave the scene quickly after mating or woman who can eat brother smaller. Actually eaten rare but if there is enough space for men to retreat. After mating, the female tarantula lay eggs 50-2000 (depending on size and type). Eggs stored in silk bags and guarded by the female until hatched offspring after 6-7 weeks. Small spiders still have some left their yolk sac and will live in that for the first day before leaving the safety of their mother's pores. Small spiders are often referred to as spiderlings.

Siberian Tigers are Endangered Animals

Siberian tiger is also known as the Amur tiger, Manchuria, Northeast China tiger and tiger Ussurian. Latin name is Panthera tigris altaicia.

Siberian tigers can reach a length of 130 inches (286 cm), which makes it the largest of the different tiger variants. Siberian Tiger also has a very broad muzzle compared with other variants of the tiger, and the male Siberian tiger usually have manes. Special body length for male Siberian tiger is 106-130 inches (233.2 to 286 cm), while females are smaller and usually live between 95 and 108 inches (209 cm and 237.6). Measured between the tiger tail. Their male Siberian tiger much heavier than the female tiger and usually weigh 419-675 lb (190-306 kg). The really big tiger Siberian male weight 800 pounds (364 kg) or more. Siberian Tiger Women tend to stay around 221-368 lb (101-168 kg).

Mantle of the Siberian tiger is orange and a little pale in comparison to the mantle of tiger subspecies other. There is also a very pale variant known as Siberian tigers White. Both variants have brown lines very much space compared with black lines and narrow space from other subspecies. White belly.

Wild Siberian tigers live in eastern Russia, northeastern China, and North Korea. Previously, wild Siberian tigers are also found in south-eastern Russia and South Korea. Siberian tigers are near extinction in the wild, but has the largest captive population of all tiger subspecies are different. Estimates claim that there are between 350 and 500 wild Siberian tigers, but we still do not know the numbers for sure. In the captive population, some 500 specimens participate in conservation programs, including the Species Survival Program (SSP). The bulk of this specimen down from 83 Siberian tigers were captured from nature. Most scholars agree that this population is large enough to be stable and genetically diverse.

Wild Siberian tiger hunt, especially deer and wild boar, and every Siberian tigers require a large area. Male Siberian tigers will try to claim the area around 800 to 1.000 km2 (309-390 mile2), while women generally claim around 100-400 km2 (39 to 154 mile2). Special environment of the Siberian tiger is the birch forest and scrub oak areas.

In Russia, the number of wild Siberian tigers are known not greater than 24 specimens in the late 1940s. In 1994, estimates show the population of Russia 150-200 tigers, and three years later this figure had risen to 360-400. Amounts increase as efforts Conservation and protected areas appointed Russia: Kedrovaya Pad, and Sikhote-Alin Lazovsky. Because Russian tigers roam over a wide area and across the Russian border, the exact number of tigers in Russia are naturally difficult to determine. The Chinese and North Korean tiger population is much smaller and estimates indicate that there are currently less than 35 Siberian tigers in China.

Cheetah The Fastest Animal in The World

The cheetah (Acinonyx jubatus) is a large cat (family Felidae, Felinae subfamily) inhabit most of Africa and parts of the Middle East. This is the only extant member of the genus Acinonyx. Cheetah can run faster than any other land animal as soon as 96-104 km / h (60 to 65 mph) in short spray covering distances up to 500 m (1,600 ft), and has the ability to accelerate from 0 to over 100 km / h (62 mph) in five seconds.

This cat is also renowned for modification at the foot of the species'. This is one of the few felids with semi-retractable claws.

Cheetah's chest is deep and narrow waist. Fur, short rough cheetah is chocolate with round black spots measuring from 2 to 3 cm (0.79 to 1.2 inches), affording it some camouflage while hunting. Nowhere under the white, but the tail has spots, which merge to form four to six dark rings at the end. The tail usually ends in a bushy white bundle. Cheetah has a small head with high-set eyes. "The sign of tears" running from the corner of his eye black down the side of the nose to its mouth still sun out of the eyes and aid in hunting and seeing long distances. Although you can reach high speeds, its body can not stand long distance running, because it is more suitable for short burst speed.

Adult cheetah weighs 21-72 kg (46-160 lb). Total head and body length is 110-150 cm (43-59 in), while the tail can measure 60-84 cm (24 to 33 in) long.

Cheetahs are 66-94 cm (26 to 37 in) tall at the shoulder. Men tend slightly larger than females and have slightly bigger heads, but there is no great variation in cheetah sizes and hard to tell male and female apart by appearance alone. Compared with similar-sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (the average is around 90 cm (35 in) tall) and so appear more slender.

Some cheetahs have large rare fur pattern mutation, acne, freckles merge. Known as the "king cheetah," they never considered a separate subspecies but in reality African cheetah, unusual patterns of their fur is the result of a single recessive gene. "The king cheetah" is only visible in some wild times, but was raised in captivity.

Cheetah paws have semi-retractable claws (known only in three other cat species: fishing cat, flat-headed cat and the Iriomote cat), offering extra grip in its high-speed chase. Cheetah claws ligament structure is similar to other cats, but that does not have a sheath of skin and fur present in other varieties, and therefore, with the exception of the dewclaw, the claw is visible. Dewclaw much shorter and straight compared to other cats.

Adaptations that enable the cheetah to run as fast as it does not include large nostrils that allow for increased oxygen intake, and enlarged heart and lungs that work together to circulate oxygen efficiently. For special catch, respiration increased speed 60-150 breaths per minute. While running, in addition to having good traction due to its semi-retractable claws, the cheetah uses its tail as a rudder as a means of steering [citation needed] In order to allow for making a hairpin curve, required to surround prey animals that often make such turns to escape.

Unlike a true big cats Pantherinae subfamily, the cheetah can snore like a breath, but can not roar. In contrast, the big cats can roar but can not snoring, except when exhaled breath. Cheetah is still considered by some to be the smallest of the big cats. Although often mistaken for leopards, cheetah does have special features, such as the long "tear-streak" lines that run from the corners of the eyes to its mouth, and places that are not "roses". Thinner body frame of the cheetah is also very different from leopards.

Cheetah is a vulnerable species. Of all the big cats, it is the most able to adapt to new environments. That always proved difficult to breed in captivity, although recently a few zoos have been successful to this success. After much hunted for its fur, the cheetah now suffers more from the loss of good habitat and prey.

Cheetah was previously considered to be very primitive in between cats and to have evolved around 18 million years ago. However, a new study shows the last ancestor of all 40 existing species of cat living is newer than about 11 million years ago. The same study showed that the cheetah, while highly derived morphological, not from a very ancient lineage, having separated from the nearest relatives live (Puma concolor, cougar, and Puma yaguarondi, the jaguarundi) around five million years ago.

This handsome felids unchanged since they first appeared in the fossil record.

Bald Eagle The Air Predator Animal

The Bald Eagle is also known as the American bald eagle or just American Eagle. Common names of birds', as well as the scientific name Haliaeetus leucocephalus, is derived from white feathers from head characteristics displayed by adult eagles. A Bald Eagle is not exactly brave, but heads bright white contrast against a dark body. The second part of the scientific name, leucocephalus, is derived from the Greek word for white, leukos, and said to the head, kephale. The first part of the scientific name, Haliaeetus, is a Latin word meaning New albatross.

In 1782, the Second Continental Congress officially stated Bald Eagle National Emblem United States. The rationale behind the choice of a few. The Bald Eagle is endemic to the continent of North America and can be found elsewhere in the world. That's also been a traditional symbol of freedom, spirit and pursuit of excellence. Ben Franklin, but suggests that the wild turkey would be a better choice, because it thought the eagle to be a bad moral character.

The Bald Eagle is one of the largest birds in North America. An adult bald eagle will be around 29-42 inches, has a wing span of 6-8 meters, and weighs 7 to 15 pounds. The Bald Eagles females grow larger than males. You can also see the difference in size between the Bald Eagles that are in different geographical areas. The Bald Eagles south tend to be smaller than their counterparts in the north.

A newly hatched Bald Eagle will have a light gray color that change color to dark brown while the chicken is still in the nest. Staining will usually completely brown after 12 weeks when the young Bald Eagle ready to fly. During the third and fourth years, the Bald Eagle will feature a speckled brown and white fur, tail, head and breast, and under his wings. White head and tail feathers from which its name is derived species will not grow up to Bald Eagle is 4-5 years. During the same period, beak and eyes dark brown birds will shift color and turn yellow.

Bald Eagles form a lifelong relationship with their partner and only search for a new mate if their partner dies. This means that they can stay together for a very long time, since Bald Eagle wild can live up to 40 years. They can grow even older in captivity. Bold Eagle couple will build a large nest together in a tall tree and return to the same nest each year. If nests were destroyed, they will usually build a new nest close to the old one. Each year, the Bald Eagle couple will make their nests even bigger by adding new building materials. It is not uncommon for a five meter nest to finally turn into the nest ten feet wide. Eagle will use twigs, grass, moss and feather soft to line their nests.

Save The Philippine Eagle Animals From Extinction

Philippine Eagle (Pithecophaga jefferyi), also known as the Monkey-eating Eagle, is an eagle of the family Accipitridae that is endemic forests in the Philippines. It has brown and white fur, and feathered crest, and generally measures 86-102 cm (2 ft 10 to 3 ft 4 in) long and weighs 4.7 to 8 kilograms (10 to 18 lb). It is considered the largest of eagles left in the world in terms of length, the Steller Sea Eagle and Harpy eagle larger in the case of bird weight and bulk.Among the rarest and most powerful in the world, has set national bird Philippines . It is very endangered, mainly due to a large loss of habitat due to deforestation in most of the coverage. Philippine eagles kill punishable under Philippine law by twelve years in jail and heavy fines.

Philippine Eagle neck adorned with long brown feathers that form a shaggy crest. These feathers give the appearance of a lion's mane, which in turn resembles the mythical griffin. The eagle has a dark face and neck cream-brown and crown. The back of the Philippine Eagle is dark brown, while the bottom and white underwings. Heavy legs yellow with large, powerful dark claws, and the prominent large, high-arched, deep beak is a bluish gray. Eagle eyes blue-gray. Adolescents is similar to adults except that they have upperpart feather fringe pale.

Philippine Eagle is usually reported as 86-102 cm (2 ft 10 in.-3 ft. 4 in.) in length, but a few studies on the natural history of the largest collections in the world found that the average is 95 cm (3 ft 1 in) for men and 105 cm (3 ft 5 in) for females. Based on a recent survey, this makes the longest extant species of eagles, as the average for the same woman with a maximum reported for the Harpy Eagle and Steller Sea Eagle. The longest Philippine Eagle reported anywhere and outside Eagle extinct Haast eagle was the longest specimens from the Field Museum of Natural History (FMNH) length 112 cm (3 ft 8 in), but it has been kept in captivity and thus may not represent individual due to differences in the availability of wild foods.

Sexual dimorfisme level in the measurement is uncertain, but believed that the male typically is about 10% smaller than the female and this is supported by the average length is available for men and women in a single source. For adult Philippine Eagles, complete weight range have been reported as 4.7 to 8 kg (10 to 18 lb), while others have found that the average is 4.5 kg (9.9 lb) for men and 6 kg (13 lb) for females. It has a wingspan of 184-220 cm (6 ft 0 in to 7 ft 3 in) and wing chord length from 57.4 to 61.4 cm (22.6 to 24.2 in). Maximum weight reported beaten by two other eagle (Harpy and Steller Sea Eagle) and wings shorter than large eagles open country (such as Martial Eagle, Wedge-tailed Eagle and Steller Sea Eagle), but quite extensive. The Tarsus of Philippine Eagle is the longest of any falcon, from12.2 be 14.5 cm (4.8 to 5.7 in) long.

The competition is huge bill but laterally compressed bill size Steller Sea Eagle to the largest living eagle bill title. This bill average 7.22 cm (2.84 in) long from the gape. The tail is long enough at 42 to 45.3 cm (17 to 17.8 in) long, while other sources list tail length 50 cm (20 in).

Voices heard most often made by the Philippine Eagle harsh, high-pitched whistle ended with derision in the field. In addition, young people have been known to beg for food by a series of high-pitched calls.

Indian Spotted Eagle a Large Bird

The Indian Spotted Eagle (Aquila hastata) is a large bird of South Asian victims. Like all typical eagles, it belongs to the family Accipitridae. Special eagles are often united with buteos, sea eagles and other Accipitridae squat more, but lately they seem less clear than eagles accipitrine more slender.

Description

The Indian Spotted Eagle is about 60 cm long and has a wingspan of 150 cm. These are broad-headed, with a wide mouth of all spotted eagles. This species has a lighter color as a whole compared with the relatives, with dark iris that make eyes look darker than wool (not vice versa as in the northern spotted eagle). Adults can be said to be separate from the Greater Spotted Eagle with lighter colors, dark eyes, and habitat preferences. After about three or four months the young birds by the end of the glossy brown head and neck feathers are soft and give the appearance that appear. The top of the tail feathers are brown with white light gives the appearance prohibited. The median feathers have spots a large beige. After about eighteen months bird moults and becomes a darker color and have a small dots. Some older teens, not like the Lesser and Greater species, do not look strong at all, make public names are quite misleading, and also lack of neck patches of cream buff teen Lesser Spotted Eagle.

Habitat

The Indian Spotted Eagle is native to Bangladesh, India, Myanmar and Nepal, where it prefers subtropical and tropical dry forests into plantations and fertile soil. These are homeless in Pakistan. In Nepal, it is the residents and breed in Chitwan and Bardia National Park, in sukla Phanta and tappu Koshi Wildlife Reserves and in some protected areas of the Terai. In India, the Ganges plains distributed skimpy top, east to Manipur, in Madhya Pradesh and south Orissa, but in the south limited Kotagiri and Mudumalai, Nilgiris district, Tamil Nadu and Tumakuru, Karnataka.

This species can often be approached closely enough for large raptors. Unlike the Greater Spotted Eagle, who was the guest of winter to Indian wetlands, this species showed no specific affinity for wetland habitats.

Harpy Eagle a Neotropical Species Animal

Harpy Eagle (Harpia harpyja), is a Neotropical species of eagle. This is sometimes known as the American Harpy Eagle Eagle to distinguish from Papua who is sometimes known as the New Guinea Harpy Eagle Harpy Eagle or Papua. This is the largest and most powerful raptor found in America, and among the remaining species of eagles in the world. Usually inhabits tropical rain forests lowland layer (appear) on the canopy. Destruction of its natural habitat has disappeared see from many parts of the former, and almost extirpated in Central America.

The top Harpy Eagle is covered with slate black feathers, and under most of the white, except for feathered tarsi, which are black ribbed. There is a broad black band across the upper breast, gray head separates from the white belly. Pale gray head, and crowned with a double crest. The upperside black tail with three gray bands, while the bottom is black with three white bands. The colored iris gray or brown or red, Cere and black or blackish bill and tarsi and feet are yellow. The hairs of men and women are equal. Tarsus is up to 13 cm (5.1 in) long.

Women Harpy Eagles typically weigh 6 to 9 kg (13 to 20 lb). A very large captive female, "A lot", weighing 12.3 kg (27 lb). Being captive, this large female may not represent weight possible in wild Harpy Eagles due to differences in food availability. Male, compared, much smaller and weighs only about 4 to 4.8 kg (8.8 to 11 lb). Harpy Eagles is 86.5 to 107 cm (2 ft 10 in-3 ft 6 in) long and has a wingspan of 176-224 cm (5 ft 9 in. to 7 ft 4 in). Between measurement standard, wing chord measure 54-63 cm (1 ft 9 in.-2 ft 1 in), the tail measure 37-42 cm (1 ft 3 in-1 ft 5 in), Tarsus is 11.4 to 13 cm (4.5 to 5.1 in.) long and Culmen hit from Cere is 4.2 to 6.5 cm (1.7 to 2.6 in). This is sometimes referred to as the largest eagle, the Philippine eagle is quite long on average and Steller's Sea Eagle a little more weight on average. The Harpy Eagle wingspan is relatively small, an adaptation that increases the ability maneuver in forest habitat and divided by other raptors in the same habitat. The Harpy Eagle wingspan that was defeated by a large number of eagles that live in more open habitats, such as the genera Haliaeetus and Akwila. The extinct Haast Eagle was significantly larger than all extant eagles, including the Harpy.

This species most quietly away from the nest. There, the adults gave a weak penetrating, melancholy scream, to call the male incubation described as Wheeeeeeeeee-wheeeeeee-wheeeeeeeee. The incubation time call girl similar but lower pitched. While approaching the nest with food, men call out "quick slit, swan-like calls, and occasional sharp shriek". Vocalization on both parents decreased as the age of the chicks, while nestlings become more vocal. The nestlings called Chi-chi-chi ... chi-chi-chi-chi, apparently the alarm in response to rain or direct sunlight. When the man approached the nest, snuggled been described as utter croaks, quacks and whistles.

Emperor Penguin Large Animal in his Species

The Emperor Penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. Men and women are equal in the fur and size, reaching 122 cm (48 in) tall and weigh anywhere from 22 to 45 kg (49-99 lb). Dorsal side and head are black and sharp reflected from the breast, white belly pale-yellow and bright-yellow ear patches. Like all penguins to fly, with slender bodies, and rigid wings and flattened into flippers for a marine habitat.

Diet consists mainly of fish, but can also include crustaceans, such as krill, and squid, like cuttlefish. In hunting, the species can remain submerged up to 18 minutes, diving to a depth of 535 m (1,755 ft). It has several adaptations to facilitate this, including normal hemoglobin structured to allow for work at low oxygen levels, strong bones to reduce barotrauma, and the ability to reduce metabolism and shut down non-essential organ functions.

The Emperor Penguin is perhaps best known for the sequence of trips made each year adults to mate and to feed their children. The only penguin species that breed during the Antarctic winter, it treks 50-120 km (31-75 miles) on the ice for the colony that could include thousands of individuals. Females lay a egg, which was incubated by the male while females return to the sea to feed, parents then take turns foraging at sea and treat their chickens in the colony. Age 20 years usually in the wild, although observations indicate that some individuals may live up to 50 years.

Emperor Penguin adults stand to 110-130 cm (43-51 in) high. Weight ranges from 22.7 to 45.4 kg (50 to 100 lb) and varies by sex, with males weighing more than females. This is the fifth heaviest living species of birds, after only deviations greater than ratite. Weight also varies by season, as both male and female penguins lose substantial mass when enlarging Tukik and brood eggs. A male Emperor penguin must withstand the Antarctic cold for more than two months to protect his eggs from extreme cold. During this entire time he does not eat anything. Most male penguins will lose about 12 kg (26 lb) while they wait for their babies to hatch. Average weight of male in the early mating season is 38 kg (84 lb) and that woman is 29.5 kg (65 lb). After the mating season is down to 23 kg (51 lb) for both sexes.

Like all penguin species, the Emperor has a streamlined body to minimize barriers while swimming, and wings that have become stiff, flat flippers. The tongue is equipped with rear-facing barbs to prevent prey from escaping when caught. Males and females are similar in size and coloring. The adults have a black dorsal feathers deep, covering the head, chin, throat, back, dorsal part of the flippers, and tail. The sharp black feather plumage light reflected from elsewhere.

The hamster from the wings and belly are white, becoming pale yellow on the upper breast, while the ear patches are bright yellow. Upper mandible of the 8 cm (3 in.) long black bill, and the lower mandible can be pink, orange or purple. In adolescence, auricularis patch, chin and throat are white, while the bill is black.The Emperor Penguin chick is usually covered with silver-gray down and has a black head and white mask. A girl with white feathers found in 2001, but not considered to be albino because do not have pink eye. Chicks weigh around 315 g (11 oz) after hatching, and fledge when they reach about 50% of the adult weight.

The Emperor Penguin feathers dark brown faded from November to February, before the yearly moult in January and February. Moulting occurs rapidly in this species compared with other birds, taking only around 34 days. Emperor Penguin feathers emerge from the skin after they have grown-third of their total length, and before old feathers are lost, to help reduce heat loss. New feathers then push out the old before completing their growth.

Survival level annual average of the Emperor Penguin has been measured at 95.1%, with average life expectancy of 19.9 years. The same researchers estimated that 1% of Emperor Penguins hatched could feasibly reach the age of 50. In contrast, only 19% of chicks survive their first year of life. Therefore, 80% of the Emperor Penguin population comprises adults five years and older.

Adelie Penguin is a Cute Animal

The Adelie Penguin (Pygoscelis adeliae) is a species of penguin common along the entire Antarctic coast. They are one of the most southerly distributed of all seabirds, such as the Emperor Penguin, South Polar Skua, Wilson's Storm Petrel, Snow Petrel that, and Antarctic Petrel. In 1840, French explorer Jules Dumont d'Urville their name to his wife, Adele.

The Adelie Penguin is one of three species in the genus Pygoscelis. Mitochondrial and nuclear DNA evidence indicates the genus split from other penguins around 38 million years ago, about 2 million years after the ancestors of the genus Aptenodytes. In turn, the Adelie penguin isolate themselves from other members of the genus around 19 million years ago.

There Adelie penguin colony 38, and there are more than 5 million Adélies in the Ross Sea region. Ross Island supports a colony around half a million Adélies. The Adelie penguins breed from October to February on shore around the Antarctic continent. Adélies rough stone nests. Two eggs are laid, it was incubated for 32 to 34 days by parents taking turns (shift typically lasts 12 days). The chicks remain in the nest for 22 days before joining Creches. The mabung chick to feather their youth and went to sea after 50 to 60 days. Adelie penguins live in groups called colonies.

This secondary penguin, be 46-75 cm (18 to 30 in) long and 3.6 to 6 kg (7.9 to 13 lb) weight is a distinctive sign of a white ring around the eyes. And feathers at the base of the bill. Long feathers hide a red bill. The tail is a little longer than other penguin tail. Appearance looks a bit like a tuxedo. They are slightly smaller than other penguin species. Their appearance closest to the stereotypical image of penguins as most black with a white belly.

Adelie penguins can swim up to 45 miles per hour (72 km / h).

Adelie penguins are preyed on by leopard seals, Skua, and sometimes, Orcas.

Like all penguins, Adelie highly social, foraging and nesting in groups. They are also very aggressive to other penguin stealing stones from their nest.

Specific behavior they documented extensively by Apsley Cherry-Garrard (who survived the journey Robert Falcon Scott's ill-fated end to the South Pole) in his book The Worst Journey in the world. Cherry-Garrard notes: "They are extraordinarily like children, these little people of the Antarctic world, either like children or like an old man, full of their own importance." Specific display their selfishness commented by George Murray Levick, Royal Navy Lieutenant-Surgeon and scientist also accompanied Scott on his ill-fated British Antarctic Expedition 1910, during his study penguins in Antarctica: "At the place where they are most often in, long terrace ice around six meters in height ran for some hundreds of meters along the water's edge, and here, just as the sea ice, many will stand near the brink. When they have successfully drive one of their ends, all will shoot out their necks to the side, and when they see peaceful outpost in the water, the rest followed. "

Observe how the intrigue penguin can also put them in danger, that Scott include specific disorder:

"The big problem with was due to the stupid behavior of penguins. Groups were constantly jumping to our floe. From the moment they landed at the feet of all those attitudes reveal curiosity devoured and pig-headed disregard for the safety of their own. they waddle-swing forward, hitting their heads to and fro in the way they usually do not make sense, even series howling dog trying to get them. "! Hulloa "they seem to say," this game - what all the silly things you want? "And they come a few steps closer. Dogs make hasty harnesses or leashes as far as possible. The penguins are not daunted in a bit, but their ruffs go up and they Squawk with angry equation.

This attitude regularly cause deaths of Adelie penguins, "Then the measures taken and developed fatal end they come within range of spring There, a grunt, horrid red patch in the snow, and the incident was closed .." Others on a mission to the South Pole is more receptive intrigue element Adélies' Cherry-Garrard.:

"Meares and Dimitri do dog-teams out on larger floes when we detained for a long time. One day a ship bound team, and they seem penguin and rushed from far off. Dogs into a panic with joy when it came to them: it should be the salutation, and their hard bark and the more they strained at their ropes, the faster it rushes to meet them. were very angry with the men who go and save him from a very sudden end, clinging trousers with its beak, and pretend to be dead beat dry bones with his flipper. "

This is the occurrence of some of the rules, "That's not unusual sights to see Adelie penguins standing in a few inches smaller than dogs nose almost panic with desire and passion."

Because of their stubbornness Cherry-Garrard personality holds in the case of a large bird, "Whatever  penguins do not have individuality, and it is revealing all his life for all to see. He can not fly away. And because he weird in all the he did, but still more because it is fighting against a greater resistance than other birds, and fought bravely always cite the most gallant pluck.

Long Tailed Gentoo Penguin Animal

Long tail Gentoo penguin, Pygoscelis papua, is a species of penguin Pygoscelis genus, most closely associated with Adelie penguins (P. adeliae) and chinstrap penguins (P. antarcticus). The first scientific description was made in 1781 by Johann Reinhold Forster on the Falkland Islands. They mention in many ways, but the most often heard is hard horn emitted with head thrown back.

Gentoo penguin adoption is unclear. The Oxford Dictionary Bahasa Inggeris noted that Gentoo used to be an Anglo-Indian term used as early as 1638 to distinguish Hindus in India from Muslims. English terms derived from Portuguese gentio (compare the "infidels"), in the 20th century the term comes constitute contempt

Gentoo Penguin easily recognized by the vast white line like carp at the top of the head and bright orange-red bill. They have a pale whitish-pink webbed feet and a tail that is long enough - the most prominent tail of all penguins. Chicks have gray backs with white space. As Gentoo penguin waddles along on land, its tail sticking behind, sweeping from side to side, then the scientific name Pygoscelis, which means "ass-tail".

Gentoos adults reach a height of 51 to 90 cm (20-36 in), making them the third largest species of penguin after the two giant species, the Emperor Penguin and the King Penguin. The male has a maximum weight of about 8.5 kg (19 lb) before molting, and a minimum weight of around 4.9 kg (10.8 lb) before mating. For women the maximum weight 8.2 kg (18 lb) before Moulting, but their weight drops to as little as 4.5 kg (10 lb) while taking care of the chicks in the nest. Birds from the north that the average 700 g (1.5 lb) heavier and 10 cm (4 in.) higher than southern birds. Southern Gentoo penguins reach 75-80 cm (30-31 in) long. They are the fastest penguin swim under water, reaching speeds of 36 km / hour. Gentoo cold acclimatised very hard.

The gentoo penguin colony is located on the surface of the ice-free. Colonies can continue to rely on the coastline but also far in the interior. They prefer shallow coastal areas and often nest between the tuft of grass. In Georgia, for example, the colony two miles inland. Whereas in colonies farther inland, where the penguins nest between tuft of grass, they move the location slightly each year because the grass may be trodden down from time to time.

Gentoos breed on many sub-Antarctic islands. Main colony in the Falkland Islands, South Georgia and Kerguelen Islands, a smaller population found in Macquarie Island, Heard Islands, South Shetland Islands and the Antarctic Peninsula. Total breeding population estimated at more than 300,000 pairs. Nests are usually made of a circular stone pile and can be quite large, 20 cm high and 25 cm diameter. The rocks are closely guarded and their ownership may be subject noisy disputes between individual penguins. They also appreciated by the women, even to the point that the male can obtain favors from women by offering himself good rock.

Two eggs are laid, both weighing about 500 g. Old part of incubation, change day-to-day tasks. Eggs hatch after 34 to 36 days. The chicks remain in the nest for about 30 days before Creches shapers. The chick skin substitute sub-adult feathers and went to sea at around 80 to 100 days.
