California sea lions lie on the docks at Pier 39 in San Francisco, Calif. on Thursday July 8, 2010. Naturalists will now be at Pier 39 to educate tourists about the California sea lions which crowd next to the piers. The recently started program is a joint effort by the Marine Mammal Center, Pier 39, and the Aquarium By the Bay. It is an effort to educate tourists and San Franciscans about Sea Lions and encourage them to do their part in helping the sea creatures. Photo: Jasna Hodzic, The Chronicle
