Ssssh! Don't wake up the sleeping California sea lion. Sea lions "raft" together with one of their pectoral flippers in the air. This behavior alters their silhouette and perhaps makes them less of a target for predatory sharks. Evidence also suggests this behavior warms or cools the body depending on the weather and sea temp
