Wildlife of Gray Wolf


Gray wolf or gray wolf (Canis lupus) is a species of canid native to the desert and remote areas in North America, Eurasia, and North Africa. This is the largest member of the family, with males on average 43-45 kg (95-99 lb), and females 36 to 38.5 kg (79-85 lb). This is similar in general appearance and proportions of the German shepherd, or sled dog, but has a large head, narrow chest, long legs, large vertical tail and claws. Wool long winter and heavy, and most of the gray-colored speckled, although almost pure white, red, or dark brown also occur.

In the genus Canis, gray wolf is a more specific and progressive smaller cousin (the coyote and wolf gold), as indicated by morphological adaptations for hunting large prey, is more like his friends and a very advanced expressive behavior. This is a social animal, traveling in the nuclear family consisting of a mated pair, accompanied by the couple's adult children. Gray wolf is a predator usually peak around the area, with only humans and tigers posing a serious threat to it. Feed primarily on large ungulates, although also eat small animals, livestock, carrion, and garbage.

Gray wolf is one of the world's most animal well examined, the books may be more written about it than any other species of wildlife. This has a long history of contact with the man, who was hated and hunted in the agricultural community for his attacks on livestock, while otherwise respected by some Native American tribes. This is a single ancestor dogs, the first didomestikasi in the Middle East. Despite prevailing fear of wolves in many human societies, most attacks have been recorded on the animal suffering associated with rabies.

Non-rabid wolves are attacking and killing people, especially children, but this is not normal, such that relatively few wolves, stay away from the people, and have been taught to fear humans by hunters and shepherds. Hunting and traps have reduced the range of the species to around third, although coverage is still relatively broad and stable population means that the species is not threatened at the global level, and therefore classified by the IUCN as Least Concern.

Gray wolf is an animal, well-knit with slim rib, very large down and leaning back. Stomach pulled in, and the muscular neck. Legs long and strong, with a relatively small distance. Front feet have five toes each, while the hind feet have four. Forelimbs that seem pressed into the chest, with elbows pointing inwards, and legs to the outside, allowing good front and rear legs on the same side to swing in the same line. Legs long enough wolves than other Canids.

This allows the animal to move fast, and allows to overcome the thick snow covering much of the geographical area. Women tend to have a narrow snout and forehead, thin neck, slightly shorter legs and less massive shoulders than males. Compared with the smaller cousin (the coyote and golden jackal), gray wolf bigger and heavier, with a wider nose, short ears, a shorter torso and long tail.

Gray wolf head is large and heavy, with wide foreheads, strong jaws and snout, long blunt. Ears relatively small and triangular. Teeth are heavy and large, are better suited to bone crushing than Canidae is still there, even though not specifically as found in hyenas. Strong canine teeth and relatively short (26 mm). Wolves can do 1,500 lbf/in2 pressure may crush compared with 750 lbf/in2 for German shepherds. This style is enough to break most of the bones. In cold weather, wolves can reduce blood flow near the skin to retain body heat. Warmth footpads arranged independently from the rest of the body, and maintained at just above the freezing point of the network, where the pads come in contact with ice and snow.

Gray wolves usually take head on the same level as the back, increasing only when the reminder. This usually travel at speeds loping, putting one foot directly in front of the other. This pace can be maintained for hours at the 8-9 km / hour, and allows the wolves to cover a great distance. On the street naked, wolves can quickly reach speeds of 50-60 km / hour. Hold a wolf running low and tilt the head slightly to one side, directing one ear to the other sides. This posture allows the wolf to continue to capitalize on the extraordinary hearing.

Gray wolves are the largest extant members of the Canidae, except for certain large domestic dog race. Gray wolf weight and size can vary around the world, tends to increase proportionally with latitude as predicted by Bergmann rule, with large Alaskan and Canadian wolves sometimes 3-6 times more weight than those Middle East and Asia southern cousins. On average, adult wolf size 105-160 cm (41-63 in) long and 80-85 cm (32-34 in) in shoulder height. The tail is ⅔ length of head and body, measuring 29-50 cm (11-20 in) long. The ears are 90-110 millimeters (3.5 to 4.3 in) in height, and the hind legs is 220-250 mm. Skull average 9-11 inches long, and 5-6 inches. Weight varies geographically wolf, on average, European wolves may weigh 38.5 kilograms (85 pounds), North American wolves 36 kilograms (79 pounds) and Indian and Arabian wolves 25 kilograms (55 pounds). Women in a given wolf population typically weigh 5-10 lbs less than males.

Wolves weighing more than 54 kg (120 lbs) are rare, though very large individuals have been recorded in Alaska, Canada, and the Soviet Union. The heaviest gray wolf recorded in North America lost on 70 Mile River in east-central Alaska on July 12, 1939 and weighed 79.4 kilograms (175 pounds), while the heaviest recorded wolf in Eurasia lost after World War II in Kobeliaky, Poltavskij District, Ukrainian SSR, and weighed 86 kilograms (190 pounds).

Gray wolves once the world's most numerous mammals distributed, after humans and lions, who lives across the northern part of the northern hemisphere from 15 ° N latitude in North America and 12 ° N in India. Deliberate human persecution have reduced the range of the species to around third, because predasi livestock and fear over attacks on humans. This species is now extinct in most of Western Europe, in Mexico and much of the United States. In modern times, the gray wolf is especially likely in the wilderness and remote areas, particularly in Canada, Alaska, and the northern United States, Europe, and Asia from around 75 ° N to 12 ° N.

Wolf population decline has been arrested since the 1970s, and has helped the development of recolonization and Reintroduksi in the range of containers, because of legal protection, land-use change and shift of rural population to the towns people. Competition with humans for livestock and game species, the concern over the dangers posed by wolves to the people, and habitat fragmentation poses a continuing threat to the species. Despite the threat, the gray wolf ranges are very wide and stable population means that the species is not threatened at the global level, and therefore classified by the IUCN as Least Concern.

Artic Wolf Animal


Arctic wolf (Canis lupus arctos), also called snow white wolf or wolf, is a subspecies of the gray wolf, mammal of the family Canidae. Arctic wolves inhabit the Canadian Arctic, Alaska, and the northern part of Greenland. They also have white fur and long canine teeth to kill prey.

Arctic wolves inhabit the Canadian Arctic and the islands, part of Alaska and the northern part of Greenland. Its habitat stretches from 70 ° North Latitude and higher. They have lived in North America for more than two million years. When they find the nest, they make some space for food and young. Arctic wolf is a subspecies of the Gray Wolf that still only be found in the entire range of the original, especially because, in their natural habitat, they rarely encounter humans. Arctic wolf is also the only subspecies of the wolf is not endangered - their remote home means that they are relatively safe from human activity, both in terms of habitat destruction and hunting.

Their habitat is very hard and isolated, and little effort of scientists to the world that during the winter season, long and dark - even the majority of Inuit live further south of the Arctic wolf. As a result, the details of their lives through many years barely known.

Arctic wolves can withstand arctic weather, with the help of their fur are really isolated. They can survive in temperatures below zero for many years, in absolute darkness for five months a year, and without food for weeks. Arctic wolves usually travel in packs of 2 to 20. They live in small family groups: breeding pair (alpha male and female) and their puppy, or a baby wolf. This package work together to feed and treat their pups. Lone Arctic wolves are young men who have left their pack to find their own territory. They avoid other wolves, unless they are able to marry. Having found an abandoned area, the only Arctic wolves will claim to mark their territory with his scent, then gather other wolf into the packaging. When the female is pregnant, she leaves pack to dig dens to raise their children. If the ice is too thick, she will move into the workspace or cave to make a home.

Like all wolves, Arctic wolves hunt in packs, preying mainly on caribou and muskoxen, but also arctic hares, seals, Ptarmigan, lemming, and small animals such as waterfowl. Due to lack of prey, they roam over large areas, with up to 2,600 km2 (1,000 sq mi), and follow the caribou migrate south for the winter, to a source of food. They are not fast runners, instead relying on stamina to register victims.

Adult wolf has 42 teeth, their main weapon in hunting. They swallow food in large discount, barely chewing it. They eat all their prey, including the bones. Wolf can eat up to 20 pounds (9 kg) of meat at one meal. When they return from the hunt, wolves regurgitate some food to hungry dogs.

Because the Arctic permafrost soil and the difficulties often posed to dig dens, polar wolves often use rocks, caves or even shallow depression in the nest instead. After around 63 days gestation to 75 days, born in late May to early June, about a month later than Gray Wolves. The mother gave birth to two or three puppies, although there may be as much as 12. This is less than wolf pups gray, with four to five. It is generally thought that the lower figure was due to prey depletion in the Arctic. Pups are born blind and deaf, and weigh about a pound. They depend on their parents for food and protection. When those 5 weeks, they are allowed outside the workspace. Other wolves in the pack can treat mom to her puppies back with food.

Wildlife of Snow Leopard


Snow leopards (Panthera uncia or Uncia uncia) is sufficiently large cat native mountains of Central Asia. Classification of this species has changed and is still classified as Uncia uncia by MSW3 in 2000 and CITES Appendix I. But with a new genetic study, snow leopards now generally regarded as Panthera uncia and classified as such by the IUCN. Classic, two subspecies have been linked but genetic differences between the two has not been resolved. Snow leopards are listed in the IUCN Red List of Threatened Species as globally Endangered (EN).

Snow leopards occupy subalpine and alpine regions generally 3,350 and 6,700 meters (10,990 and 22,000 ft) [9] above sea level in Central Asia. The Snow Leopard Survival Strategy (McCarthy et al. 2003, Table II) compiled national snow leopard population estimates, updating the work Fox (1994). Many of the estimated gross and acknowledged to be outdated, but the total estimated population of 4.080 to 6.590. [10] However, snow leopards global effective population size (which tend to reproduce) suspected to be less than 2500 (50% of the total population, or 2.040 to 3.295).

Snow leopard tiger is slightly smaller than the other big cats but, like them, show a variety of sizes, usually weighing between 27 and 55 kg (60 and 120 lb), with large males occasionally exceed 75 kg (170 lb) and little girls under 25 kg (55 lb). They have a relatively short body, measure the length from head to tail of 75 to 130 centimeters (30 to 50 in.). However, the tail long enough, at 80 to 100 cm (31-39 in), with domestic cats only marble sized relatively longer tail. They are big cats stocky and short-legged, standing about 60 cm (24 inches) at the shoulder.

Snow leopards have long thick fur, and their base color varies from smoky gray to yellowish tan, with white hamster. They have dark gray to black open roses on their body with small spots of the same color on their heads and places greater on their legs and tail. Common among cats, their eyes are pale green or gray in color.

Snow leopards show several adaptations of living in a cold mountainous environment. Their bodies are stocky, their fur thick, and their ears small and rounded, all of which help to minimize heat loss. Their paws are wide, which distributes their weight better for walking on snow, and have fur on their undersides to increase their grip on steep and unstable surfaces, but also helps to minimize heat loss. Snow leopards tail 'long and flexible, helping them to keep their balance, which is very important in the rocky terrain they inhabit. Their tails are also very thick due to storage of fats and are very thick covered with fur which allows them to be used like a blanket to protect their faces when asleep.

Snow leopard has a short muzzle and domed forehead, containing unusual nasal cavities that help the animal breathe in large thin air conditioners their mountainous environment.
Snow leopards can not roar, despite having hyoid bone part ossifications. This partial ossifications previously considered important in order for the big cats to roar, but new studies show that the ability of nervousness is due to the morphological characteristics of others, especially from the larynx, which are absent in the snow leopard. Vocalizations including snow leopards hiss, chuffing, Mews, growls, and wailing.

Indian Leopard is Leopard Subspecies Animal


Indian leopards (Panthera pardus fusca) is a leopard subspecies widely distributed on the Indian subcontinent and is classified as near threatened by the IUCN since 2008. Panthera pardus species may soon qualify for Vulnerable status due to habitat loss and fragmentation, heavy poaching for illegal trade of skins and body parts of Asia, and persecution because of a conflict situation. They are becoming increasingly rare outside protected areas. Tendency population declined.

Indian leopard is one of the five big cats found in India, apart from Asiatic lion, Bengal tiger, snow leopard and clouded leopard.

In 1794, Friedrich Albrecht Anton Meyer wrote the first description of Felis fusca, in which he gave an account panther-like cat from Bengal from about 85.5 cm (33.7 in), with strong legs and a well-formed tail length, head as much, The panther wide nozzle, short ears and small, yellowish gray eyes, light bulb eyes gray, black at first glance, but on closer inspection a dark brown with spots dark circles, under red colored pale.

India leopard Men grow between 4 ft 2 in (127 cm) and 4 ft 8 in (142 cm) in body size by 2 feet 6 inches (76 cm) to 3 ft (91 cm) long tail and weigh between 110 and £ 170 (50 and 77 kg). Smaller females grow between 3 ft 5 in (104 cm) and 3 ft 10 in (117 cm) in body size by 2 feet 6 inches (76 cm) to 2 ft 10.5 in (87.6 cm) long tail and weigh between 64 and 75 lb (29 and 34 kg).

In the Indian subcontinent, topographic barriers to the spread of this subspecies is the Indus River in the west, and the Himalayas in the north. In the east, the course of the Brahmaputra and the Ganges Delta formed a natural barrier to the distribution of leopards Indochina. Indian leopards are distributed throughout India, Nepal, Bhutan, Bangladesh and parts of Pakistan. In sympatric with their Himalayan snow leopards to 5,200 meters (17,100 feet) above sea level. They inhabit tropical rain forests, dry autumn forest, temperate forests and northern coniferous forests but does not occur in the Sundarbans mangrove forest.

American Crocodile is Neotropics Animal


American Crocodile (Crocodylus acutus) is a species of crocodile found in Neotropics. This is the most extensive of the four extant species of crocodiles from the Americas. Populations occur from the Atlantic and Pacific coast of southern Mexico to South America as far as Peru and Venezuela. It also lives in many river systems in Cuba, Jamaica, and Hispaniola. In the United States, the American crocodile habitat is limited to the southern part of Florida, and has an estimated population of 2,000. American crocodile habitat consists mainly of coastal areas. This is larger than some other crocodile species, with some males reach a length of 6.1 m (20 ft).

Like all crocodiles, American crocodiles are quadruped, with four short, unfold the legs, tail, strong long and scaly hide with rows of stiff Scutes flowing back and tail. Elongated nozzle and including a pair of strong jaws. His eyes were pengerjap membranes for protection along with the tear glands, which produce tears.

Nostrils, eyes, and ears are situated on the top of his head, so that the entire body can be concealed underwater for surprise attacks. Camouflage also helps that prey on food. Relatively long and narrow snout of the American alligator, despite wide average compared to the Orinoco crocodile. American crocodiles are also paler and more gray than dark-colored crocodile relative. This species usually crocodile crawling on belly, but also can "walk tall". Larger specimens can fill up to 10 mph (16 km / h).

They can swim at 20 mph (32 km / h) by moving their body and tail with a meandering way, but they could not maintain this speed.

American crocodiles are more vulnerable to cold than American alligators.  While the American alligator can survive in water from 7.2 ° C (45.0 ° F) for some time, an American alligator in an environment that will be helpless and lost. American Crocodile, however, have a faster growth rate than alligators, and far more tolerant of salt water.

Tukik newborn about 22 cm (8.7 in) long and about 60 g (2 oz) in mass. The average adult is 4.3 m (14 feet) and weighs 382 kg (840 lb) in males, and 3 m (9.8 ft) and 173 kg (380 lb) in females.

In Tarcoles River in Costa Rica, tens of four meters and five meters in some individuals crossing the bridge often (where they eat every day, which may have helped them achieve the consistent large size) and is a popular tourist attraction. In Florida they range, adult length has been recorded as high as 5.2 m (17 feet), but the adult male average size of 4.3 m (14 feet) long. This species is said to grow largest in the river valley in South America, but even the old man who rarely reach 6 m (20 ft).

A skull of this species is found to measure 72.6 cm (28.6 in) and is estimated to have been owned by a crocodile than 6.6 m (22 feet) long. Large, regular adult male weighs around 400-500 kg (880-1100 lb), with individuals from six meters or more than 1,000 kg (2,200 lb). In 2009, two biologists in Florida to work for The History Channel series Monsterquest seen and filmed what they are expected to be 16-18 meters deep in the Everglades alligator.

American crocodiles breed in late autumn or early winter, involved in a protracted mating ritual in which the male emits a very low frequency bellows to attract females. Body size is more important than age in determining the reproductive ability, and females reach sexual maturity at length about 2.8 m (9.2 ft).

In February or March, the female will begin to make a nest of gravitational sand, mud, and dead vegetation along the water's edge. Nest location is very important, and with the right amount of plants, the eggs will grow in a small temperature range. Because the temperature dependent sex determination in alligators, slightly above the temperature deviation can result in traction of all-male or all female, which may be harmful to people's health. About one month later, when it's time to put, females will dig a hole to the side of the diagonal width of the nest and lay 30 to 70 eggs in it, depending on the size of his body.

After laying, the female may cover the eggs with debris or leave them uncovered. The, egg whites long if need be explained is about 8 cm (3.1 in) long and 5 cm (2.0 in) wide and has a number of pores in the skin fragile. During the 75 to 80 day incubation period for, parents will take care of the nest, often occupying the hole in the nearest bank. Women especially have been known to keep their hives with violence. But regardless of the precautions, crocodile eggs are sometimes victims of raccoon, fox, skunk or other pemulungan mammals. Crocodile eggs quite fragile, but softer than bird eggs. Young species hatch after 75-80 days.

These species are mainly in tropical regions with distinct wet season, and the young hatch near the first rainy season (July-August), after previously dry season and before the body of water in which they live flood. In the development of the children, the mother crocodile show a unique mode of care. During the process of hatching, while young crocodiles most vulnerable to predation, instinctively they will call in a soft, grunting like croaks. This sounds trigger women to attend to their nests, eggs reveal if they have been closed. Then it will help Hatchlings in their egg and spoon them escape with his mouth, bringing them into nearby water sources.

The Hatchlings, which is 24 to 27 cm (9.4 to 11 in) long, have been reported to actively hunt their prey in a few days after hatching. It is not uncommon for parents to treat young weeks even after they have hatched, still call attention to them and continue to provide transportation. Around five weeks after hatching, young crocodiles disperse find their own independent lives. Most of them, of course, will not survive, which is eaten by wild birds a greater variety of fish. Those who do take place early stages of life will grow rapidly, feeding on insects, fish and frogs. In addition, several young crocodile rumored to be eating each other.
