A female seal is called a cow, her mate is a bull and her babies are pups; during breeding season, the three are part of a harem. There are numerous species of seals, including elephant, fur and leopard varieties.
Female seals deliver one pup each year. The pup nurses from four days to one month, during which time the female does not eat. She uses stored blubber for energy. After weaning, a pup learns to swim and hunt entirely on its own with instinct as his guide. Seals are warm-blooded marine mammals that live in ocean waters at all latitudes.
