Baleens are a structure that replaces teeth and allows the animals to filter out tiny plankton organisms, krill.

Fin whales perform prolonged apneas varying from 5 to 15 minutes and, when diving, rarely show the caudal fin out of the water.<br>The fin whale is distributed throughout temperate, pelagic waters, although it is sometimes observed at shallower depths.
