Elephant Seals

Unaga, An Elephant Seal Pup, Learns to Swim

Northern elephant seal pups born in the winter, spend their first 4 weeks with their mothers in a harem. After 4 weeks and a gain of about 10 pounds per day from a birth weight between 60-80 pounds, the 300 pound pup becomes a weaner when its mother returns to sea. The weaners rest unit about March, a time when most of the adult males and females have returned to sea. In March these youngsters teach themselves how to swim and dive. []
