Blue Whales :: Biology Ecology Nature

gamey WhalesThe sick monster is the largest creature of the sea, in fact, it is thelargest creature known to man. Contrary to what most people think, stock-still though blue air track downs live in the sea, they are mammals. Theybreathe air, have their babies born alive and can live anywhere from 30to 70 years. The dingy titan is a baleen track down, and instead of havingteeth, Blue whales have around 300-400 baleen plates in their mouths.They fall under the category of the rorquals, which are the largest ofthe baleen family. The scientific reference of the Blue whale is,Balsenoptera musculus.Introduction Whales are separated into two groups, the baleen and thetoothed whales. The olive-drab whale is the largest baleen whale and thelargest animal that always lived on Earth, including the largestdinosaurs. Baleen are rows of coarse, bristle-like fibers used tostrain plankton from the water. Baleen is made of keratin, the samematerial as our fingernails. They live in po ds, the have twoblowholes. The blue whale has a 2-14 inch (5-30cm) thick layer ofblubber. Blue whales (Balaenoptera musculus) are baleen whales(Suborder Mysticeti). They are one of 76 species and are marinemammals.Background The Blue whale is called a rorqual, a Norwegian word forfurrow referring to the pleated grooves running from its chin to itsnaval. The pleated throat grooves allow the Blue whales throat to fatten out during the huge intake of water during filter feeding they canhold 1,000 tons or more of food and water when fully spread out (Small1971). Blue whales have 50-70 throat grooves.Blue whales grow up to about 80 feet (25m) long on average, weighingabout 120 tons. The females are loosely bigger than the males, thisis the case for all baleen whales. The largest specimen found was afemale 94 feet (29m) long weighing more than 174 tons (Satchell1998). The head of the Blue whale forms up to a quarter of the totalbody length. Compared with other rorquals, the he ad is very broad.The blue whale heart is the size of a vitiated car and can pump almost 10tons of blood throughout the body. They have a very small, falcate(sickle-shaped) dorsal fin that is primed(p) penny-pinching the fluke, or tail.Blue whales have long, thin flippers 8 feet (2.4m) long and flukes thatare 25feet (7.6m) wide.The blue whales skin is usually blue- old with white-gray spots. Theunderbelly has brown, yellow, or gray specks.Blue Whales Biology Ecology NatureBlue WhalesThe Blue whale is the largest creature of the sea, in fact, it is thelargest creature known to man.
