Elephant seals are large marine mammals known for their size and distinctive features. Males can weigh up to 5,000 pounds and have a large, trunk-like nose, while females are smaller, averaging around 1,500 pounds. They primarily inhabit the coasts of the Pacific Ocean and are known for their impressive diving abilities, reaching depths of over 5,000 feet in search of food. These seals are known for their seasonal breeding behavior, with males establishing territories during the breeding season. They primarily feed on fish and squid, using their whiskers to detect prey in the dark ocean depths. Elephant seals can hold their breath for over an hour while diving.
