The fin whale is a large marine mammal that is found throughout ocean waters worldwide. The fin whale is the second largest whale in the world behind the blue whale, and also the second largest animal on Earth
There are two different species of fin whale which are the Northern fin whale and the Antarctic fin whale.
Both fin whale species are very similar in appearance but the Antarctic fin whale tends to be larger in size than the Northern fin whale.
The fin whale is a carnivorous animal, that feeds by filtering food out of the water using the specially designed plates in its mouth (like a blue whale). The fin whale eats fish, krill, plankton, squid and crustaceans by simply opening its enormous mouth and swimming at faster speeds.
Due to its sheer size, the fin whale has no real predators within its natural environment as ocean predators simply don't compare in size. Humans are the greatest threat to the fin whale, as they have been hunted over the years to near extinction. The new-born fin whale calves are also sometimes attacked by large sharks.
Fin whales breed in the cold winter months, after which the female fin whales migrate south to the warmer, safer waters where she can nurse her young. The fin whale calf is born after a gestation period last is nearly a year long, and feeds on his mothers milk until he is around 7 months old and able to start hunting in the water.
