Fishermen and swimmers sure have seen a lot of sea lions — some of them snatching salmon off lines or nipping freestylers in the bay — but a study published Wednesday proves the blubbery pinnipeds are, in fact, all over the place. The sea lion population has not only rebounded after a series of catastrophes — including a lack of food and algae poisonings — but the approximately 281,450 sea lions now living along the California coast have reached carrying capacity, according to scientists with the National Oceanic and Atmospheric Administration.
