SAN FRANCISCO (AP) — The Latest on sea lion attacks on swimmers in San Francisco Bay (all times local): 2:30 p.m. A swimmer bitten by a sea lion in San Francisco says he believes the animal trailed him as he swam from the beach to the mouth of a cove where he was attacked. Christian Einfeldt tells San Francisco television station KGO that when he turned around to swim back Thursday, the massive sea lion was right there. Einfeldt says he felt threatened but was a quarter-mile from shore and there was nothing he could do. The sea lion bit him on the upper right arm and he started bleeding.
