southern elephant seal

The southern elephant seal (Mirounga leonina) is one of the two extant species of elephant seals. It is both the largest pinniped and member of the order Carnivora living today, as well as the largest Antarctic seal. The seal gets its name from its great size and the large proboscis of the adult males, which is used to make extraordinarily loud roaring noises, especially during the mating season. Rather larger at average than the male northern elephant seal (Mirounga angustirostris) (which is 40% lighter) and male walrus (Odobenus rosmarus) (the average North Pacific bull, of the larger race, is 2.5 times lighter), the adult bull southern elephant seal is without rival the largest carnivoran alive. An average adult male southern elephant seal weighs six to seven times more than the largest terrestrial carnivorans, the polar bear (Ursus maritimus) and Kodiak bear (Ursus arctos middendorffi).
