The stones help to retain water in the body.. Some other theories are that they help to grind fish or help ward off hunger pangs when the animals are fasting on the shore. The stones may also have been swallowed by accident and be of no use at all.
Lanugo. Sea lions usually give birth to only one pup a year. The lanugo is a thick coat of hair which helps to keep the pup warm till it develops a layer of blubber.
A raft. During mating season, adult males called bulls try to coerce as many female cows as possible to form their harems. The largest and strongest bulls maintain their harems while the remaining bulls called bachelors are driven elsewhere. Like most mammals, sea lions are polygynous.

Harbor seals will usually snort and even sneeze to show who is dominant or to scare off predators. The pups usually make "sheep-like cries" to attract their mother's attention. These are often a sign that it's time for feeding.
