PETER J. ADAM; University of California, Los Angeles, Department of Ecology and Evolutionary Biology All marine mammals, with the exception of herbivorous sirenians and (arguably) desmostylians, prey on other animals ranging in size and diversity from copepods to fish and squid to other marine mammals. Owing to their predatory habits, cetaceans, pinnipeds, and sea otters can be grouped together into a marine mammal carnivore guild
