Sea lion pups develop quickly thanks to their mother's milk which is composed of fifty percent fat.
Sea lions have large, bare flippers which they use to help regulate their body temperatures. Dense fur, a mixture of permanent underfur and longer top hairs that are shed annually, covers the rest of their body. Sea lions can dive to depths of six hundred feet, much deeper than other seals, to hunt for fish like herring, anchovy, and squid. They tend to keep to themselves at sea, but their breeding grounds on land get pretty packed. Most head for the breeding ground by May and babies are born in June. Males, or bulls, are polygamous, which means they mate with more than one female. Substantially larger than females, bulls are also pretty forceful; they set up their own territories and aggressively herd females and drive away other bulls. Sea lions have a lifespan of nearly thirty years.
