SEA LIONS ABOUT-FACE TO SIZE UP STRANGE INTRUDERS Large, external ears distinguish these animals from other seals. Hunters club hundreds of pups to death each yearfor skins, most valuable when taken from babies under 20 days old. Men enter dark sea caves where the young are born; there they would be hopelessly trapped if thewater should rise upon them. This herd summers on the rocky ledges of Offing Island.
