Either of two large seals, Mirounga angustirostris mainly of Pacific coastal waters of California or M. leonina of coastal waters of the Southern Hemisphere, the males of which have an inflatable, trunklike proboscis. Also called sea elephant. Either of the two largest pinniped species: the northern elephant seal (Mirounga angustirostris), of coastal islands off California and Baja California, or the southern elephant seal (M. leonina), of sub-Antarctic regions. Both are gregarious earless seals. The male has an inflatable, trunklike snout. The northern species is yellowish or gray-brown, the southern species blue-gray. Males of both species reach a length of about 21 ft (6.5 m) and a weight of about 7,780 lbs (3,530 kg) and are much larger than the females. Elephant seals feed on fish and squid or other cephalopods. During the breeding season, bulls fight to establish territories along beaches and to acquire harems of up to 40 cows
