How big does a Northern elephant seal get? Here is an overview over the average adult age:
A grown Northern elephant seal (Mirounga angustirostris) reaches an average size of 3.72 meter (12′ 3″).
When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 20.25 years, they grow from 34.39 kg (75.82 lbs) to 1116.2 kg (2460.79 lbs). A Northern elephant seal has 1 babies at once. The Northern elephant seal (genus: Mirounga) is a member of the family Phocidae.
As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.
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.
