Description

The huge male northern elephant seal typically weighs 1,500–2,300 kg (3,300–5,100 lb) and measures 4–5 m (13–16 ft),although some males can weigh up to 3,700 kg (8,200 lb).Females are much smaller and can range from 400 to 900 kg (880 to 1,980 lb) in weight,or roughly a third of the male's bulk,and measure from 2.5 to 3.6 m (8.2 to 11.8 ft).The bull Southern Elephant Seals are,on average,larger than those in the Northern species but the females in both are around the same size,indicating the even higher level of sexual dimorphism in the Southern species.Both adult and juvenile elephant seals are bar-skinned[discuss] and black before molting.After molting,they generally have a silver to dark gray coat that fades to brownish-yellow and tan.Adult males have hairless necks and chests speckled with pink,white and light brown.Pups are mostly black at birth and molt to a silver gray after weaning
