SAN FRANCISCO (AP) — Four dead gray whales have washed onto San Francisco Bay Area beaches in the last nine days.
Experts say the carcass of a 41-foot adult female gray whale landed at San Francisco's Crissy Field on March 31.
A second adult female was found last Saturday in Moss Beach in San Mateo County.
A third was found Wednesday floating near the Berkeley Marina and the following day one washed up in Marin County's Muir Beach. Friday's whale was struck by a ship.
Experts haven't determined how the other three died.
