In December Elephant seals, male and female, come down from Alaska to the beaches of SoCal islands to breed. The males leave pretty soon after their business is done (there isn’t a March of the Seals, to be sure) leaving the ladies to raise the babies. The females don’t eat during breeding or raising. When the pups are weaned, the females go swimming for a couple of months to eat. Then they come back to the islands and shed their skin. When this is done they swim back up to the Alaska, never getting out of the water until it’s time to breed again.
During the three weeks their skin is flaking off, the elephant seal females don’t eat. They just sit on the beach, lounging around.
