The Northern Elephant Seal (Mirounga angustirostris) is one of two species of elephant seal (the other is the Southern Elephant Seal). It is a member of the Phocidae ("true seals") family. Elephant seals derive their name from their great size and from the male's large proboscis, which is used in making extraordinarily loud roaring noises, especially during the mating competition. There is a great sexual dimorphism in size, with the males (bulls) reaching five meters in length, much bigger than the females (cows), who average about three meters. The males average 1, 800 kg (4000 lb), while the females average 650 kg (1400 lb). Correspondingly, there is a highly polygynous mating system, with a successful male able to impregnate up to 50 females in one season. -Wikipedia
