Seal

Seals are air-breathing mammals that are at home on beaches, rocky shores, and in the sea. They are able to dive to depths exceeding 600 feet and can remain submerged for over 20 minutes. Seals are graceful and efficient swimmers, because they use their hind flippers for propulsion and fore-flippers as rudders. Movement on land is slow and difficult. They have a loud bark that identifies them. They often huddle in family groups on the shore.
