This seal is widespread in pack ice around Antarctica. It feeds mainly on krill; despite its name, crabs are not its principal food.
It has a slender body and a long snout. Its fur ranges from dark brown to blonde and becomes lighter in summer. Projections on its teeth help sieve krill from the water.
