The sea hare, or bearded seal, is a large Arctic seal. It has very long whiskers on its muzzle, which help it search for food on the sea floor.
The sea hare differs from other seals with its very long and thick whiskers. It is important for Arctic nature as prey for polar bears and as a consumer of bottom-dwelling animals.
