Fin Whale
(Balaenoptera physalus)
Fin whales are the second largest species of whale and the second largest
animal ever to have lived. Fin whales (also know as finback whales) can
reach lengths of over 80 feet and weights of more than 160,000 lbs in the
northern hemisphere and over 85 feet and 170,000 lbs in the southern hemisphere
and are distributed around the world except for the tropics, i.e., they
have an antitropical distribution.
Fin whales feed on a wide array of prey species, depending upon availability,
ranging from small schooling fish such as sand eels, herring and tinker
mackerel, to crustaceans such as krill and copepods, to squid. A variety
of feeding techniques are employed in order to concentrate prey, essentially fin
whales are "gulpers," taking in large quantities of food and water in each
mouthful.
