Northern Elephant Seal (phocid) Mirounga angustirostris
Elephant seals got their name because adult males have large noses that resemble an elephant's trunk, called a proboscis. Males begin developing their proboscis at three to four years of age (at sexual maturity), and it is fully developed by seven to nine years. The elephant seal is in the phocid, or true seal, family. It lacks external ear flaps and moves on land by galumphing. The elephant seal has a round face with very large eyes. Pups are born with a black coat which then molts at the time of weaning (28 days), turning a silver-gray.
Northern elephant seals are found in the North Pacific from Baja California, Mexico to the Gulf of Alaska and Aleutian Islands. During the breeding season, they live on beaches on the Channel islands and a few remote spots on the mainland. The rest of the year, except for molting periods, elephant seals live well off-shore.
It is believed that Northern Elephant Seals eat deep-water, bottom-dwelling marine animals such as ratfish, hagfish, Pacific whiting, small sharks, spiny dogfish, eels, rockfish, pelagic red crab and squid.
