Average life span in the wild: 20 years. Size: 5.25 to 6.25 ft (1.6 to 1.9 m). Weight: 400 lbs (180 kg). Group name: Colony or rookery. Size relative to a 6-ft (2-m) man: Harp seals spend relatively little time on land and prefer to swim in the North Atlantic and Arctic Oceans. These sleek swimmers cruise the chilly waters and feed on fish and crustaceans.
