Oceanic Society introduces an exploration of SF Bay that will explore this unique ecosystem and explain the Bay's role as a habitat for nesting birds and marine mammals. The emphasis will be on the megafauna (animals that weigh more than 100 pounds) of the Bay including porpoises, seals, dolphins and sharks. Each each trip will be led by an experienced Oceanic Society Naturalist who will talk about the history of Angel Island, Alcatraz, Pt. Bonita Lighthouse and Yerba Buena Island. You are invited to join us for a 3 hour cruise on Sunday mornings from 9:30 a.m. to 12:30 p.m. Adults are $54.95 and children six and older with their parents are $49.95. Please call our office at 415-256-9941 for more information or visit our website.
