The fin whale is the second largest mammal in the world, just behind the blue whale. They are nicknamed “razorback” due to their distinctive dorsal fin. They also have a unique coloration on their jaw that is thought to help them catch fish and krill.
Commercial whaling is the main threat to this species.
