Seal

Seals are marine mammals with streamlined bodies, flippers and insulating fat beneath the skin. True seals lack external ear flaps and move on land by undulating their bodies. They feed on fish, squid and other aquatic prey, according to species and habitat. Time in the water alternates with resting, breeding or molting on beaches, rocks or ice. Sensitive whiskers help detect movements in the water. The common name is sometimes used broadly for several pinnipeds, although true seals form a distinct family.
