Habitat
Fin whales inhabit all major oceans, preferring deep, offshore waters in temperate and polar regions. They are often found in areas with high productivity for feeding, such as upwelling zones, and migrate seasonally between polar feeding grounds and tropical breeding areas.
Diet
Fin whales primarily feed on krill, small schooling fish like herring and capelin, and squid. They use baleen plates to filter food from large volumes of water in a lunge-feeding technique, typically during the summer in polar regions when prey is abundant.
Behavior
Fin whales are highly migratory, traveling thousands of miles between feeding and breeding grounds, often alone or in small, loose groups. They are generally active day and night, communicating with low-frequency sounds that can travel long distances, and exhibit breaching or slapping behaviors on the surface. They are not highly territorial but may form temporary aggregations in rich feeding areas.
Conservation Status
The IUCN lists the fin whale as Vulnerable, with population trends showing slow recovery in some regions due to past whaling but ongoing threats from ship strikes, entanglement in fishing gear, and climate change.
