Thefin whale (Balaenoptera physalus) is a hugebaleen whale. It is the second largest animal onEarth (theblue whale is the biggest). This whale is sometimes called the "greyhound of the sea" because of its fast swimming speed; it can swim up to 23 mph (37 km/hr) in short bursts. The fin whale is also called the finback, finner, razorback, common rorqual, and herring whale.

The fin whale is a streamlined whale that is found worldwide; it is most common in the North Atlantic. There are three separate populations of fin whales, one in the North Pacific, one in the North Atlantic, and one in the Southern Hemisphere; they do not interbreed. Many groups of fin whales migrate between feeding grounds and breeding grounds. This whale usually swims in pods of 3-7 whales but larger groups (up to 300 animals) may form at rich feeding grounds.

Diet and baleen

[change |change source]

Fin whales arefilter feeders that eatplankton (tinycrustaceans likekrill andcopepods) and small fish from the water. They have very fine grey-black baleen that traps very small particles of food. Each side of the upper jaw has 270-470 baleen plates.
