A sea lion bit a pair of swimmers in Venice Beach last night, in what lifeguards say may be the first case of such an event occurring in the area. KTLA reports that a woman was bit on the leg around 6:30pm; her husband came to her aid, only to be bitten on his hands, feet, and head. The pair, both in their 60s, was treated at a hospital and released. In other frightening California beach news, a two-mile stretch of Mission Beach was closed in San Diego after a great white shark was spotted. (More Venice Beach stories.)
