SALINAS, Calif., Nov. 9 (UPI) -- Bottlenose dolphins are likely responsible for the growing number of dead porpoises appearing on California beaches, marine biologists said.
Daniela Maldini, chief scientist with the Okeanis conservation group, said her group shot footage in September of a porpoise being fatally attacked by a group of dolphins, KTVU-TV, Oakland, Calif., reported.
