Abstract
A group of at least 17 killer whales (Orcinus orca) were observed attacking a gray whale (Eschrichtius robustus) mother and calf on 2 May 1992 in Monterey Bay, California, U.S.A. (36°47.90′N, 122°00.17′W). Small groups of killer whales took turns harassing the gray whales and prevented them from leaving the area. Three of the killer whales participating in this attack previously had been photographed on 6 August 1989 in Glacier Bay, Alaska, U.S.A. (58°41′N, 136°04′W). This linear distance nearly doubles the maximum range of movement previously reported for killer whales.Keywords
