Species: Balaenoptera physalus
Length: 20 to 24 meters.
Weight: 40 to 85 metric tons.
Life expectancy: 75 to 100 years.
Diet: Feeds on euphausids and also on capelin and sand lance, and juvenile herring.
Behaviour: Solitary, or in groups of 6-12 individuals. Fin whales rarely raise their flukes above the surface of the water on a terminal dive, and rarely display aerial behaviors such as breaching, unlike the humpback whales. Fin whales typically complete a series of shallow dives, surfacing several times within one to two minutes, before taking a terminal dive which can commonly last between 8 to 12 minutes.
