The elephant seal is a large marine mammal known for its distinctive size and shape. Males can weigh up to 4,500 pounds and are recognized by their large, trunk-like noses. These seals are found primarily in the North Pacific Ocean, where they spend most of their lives at sea, coming ashore mainly for breeding and molting. There are two species of elephant seals: the Northern elephant seal and the Southern elephant seal. Both species are known for their impressive diving abilities, capable of reaching depths of over 5,000 feet in search of food, primarily fish and squid.
