Field observations are a fundamental method to increase our knowledge of orcas in the Gulf of California, for which little is known about their feeding habits and behavior. Before this paper orca predation on rays and sharks had already been recorded within the Gulf of California, but only anecdotally and without descriptions or information of hunting tactics. Here we present a graphical and behavioral description of orcas used to techniques to feed on four different species of rays. The fact that the same individuals were involved in different predation events could suggest that some orcas specialize in preying on rays in the Gulf of California.
