mammal
Also known as: Mirounga angustirostris

Quick Summary

The northern elephant seal (Mirounga angustirostris) is one of two species of elephant seals, which are the largest pinnipeds (aquatic mammals). These seals are named for their large size and the male's inflatable, trunk-like snout. The northern elephant seal is found off the coast of California and Baja California, while the southern elephant seal inhabits sub-Antarctic regions.

Males of both species are significantly larger than females, reaching lengths of about 6.5 meters and weights of up to 3,530 kg. They primarily feed on fish and squid. During the breeding season, males become aggressive, fighting for territories and harems. Females give birth to a single pup annually. Historically, elephant seals were hunted extensively for their oil, nearly driving them to extinction in the 19th century. However, conservation efforts have led to population recovery, and their survival is no longer considered threatened.12
