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.
