Most of the oxygen-rich blood is directed away from the outer parts of its body, like the flippers. It is pumped to the brain and heart, where it is really needed. Bulls, Cows and Pups Male seals are called bulls, and females, cows. The males of some kinds of seals, like elephant and gray seals, look very different from the females. This is important during the breeding season.
Larger males guard an area of beach and mate with female s who come ashore there.
They do not even leave their territory to eat. They threaten, chase and fight other males who trespass. The strongest males father next year's pups. The bulls and cows of most seals, though, are hard to tell apart. Harbor seals are a good example of this.
