Fin Whale

Fin whales are the second largest whale species, only surpassed by their close relative, the blue whale. 

Known as ‘finback’ or ‘razorback’ whales due to the distinctive ridge that runs from their dorsal fin to their tail, fin whales are sleek, streamlined, and marked with lighter patterns on their backs. Once heavily hunted during the industrial whaling era, these magnificent marine mammals are now a highlight of Arctic and sub-Arctic wildlife encounters, gliding through cold offshore waters in search of food and seasonal breeding grounds.

Diet and Behaviour

Fin whales feed primarily on small schooling fish, krill, and plankton. Using a combination of lunge feeding and filter feeding, they can consume vast quantities at a time. 

These whales are fast swimmers and highly migratory, often moving seasonally between feeding and breeding areas. Their streamlined bodies and pointed heads make them well-adapted to life in cold, open waters, and they are often seen surfacing gracefully, displaying their tall, curved dorsal fin.

Breeding Cycle 

Fin whale mating follows a seasonal pattern. In the Northern Hemisphere, mating typically occurs between December and February, while in the Southern Hemisphere, it takes place between May and July. Gestation lasts roughly 11 months, resulting in the birth of a single calf. Despite their widespread distribution, many aspects of fin whale migration, social behaviour, and population dynamics remain poorly understood, making each sighting a remarkable and educational experience for expeditioners.
