A fast baleen whale capable of 40 km/h bursts, it filters krill and small fish and is listed Vulnerable after decades of commercial whaling.

Feeding behaviour

Foraging strategy varies by season. Fin Whales may hunt, graze, filter-feed, or scavenge depending on ecology.

Role in the food web

As mammals, they interact with predators, prey, and competitors across their range.

Human-related feeding risks

Never feed wild fin whales — it habituates animals to people and can spread disease.
