Pups and Calves

A baby seal or sea lion is called a pup. A baby walrus is called a calf. Pups and calves are born on land or in the water. They grow rapidly on their mother’s rich milk. Soon they enter the sea to develop their survival skills. They learn to swim, dive, catch prey and haul out.

The first year of life at sea is the most difficult. Finding enough food, surviving storms at sea, escaping pedators and withstanding disease, are all potential hazards these young animals face.
