It is hard to guess what a Northern elephant seal weights. But we have the answer:
An adult Northern elephant seal (Mirounga angustirostris) on average weights 1116.2 kg (2460.79 lbs).
The Northern elephant seal is from the family Phocidae (genus: Mirounga). It is usually born with about 34.39 kg (75.82 lbs). They can live for up to 20.25 years. When reaching adult age, they grow up to 3.72 meter (12′ 3″). Usually, Northern elephant seals have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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 family Phocidae (true seals). 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. Sexual dimorphism in size is great. Correspondingly, the mating system is highly polygynous; a successful male is able to impregnate up to 50 females in one season.
