Distribution, feeding habits and morphology of killer whales <scp> O </scp> rcinus orca in the <scp>C</scp>aribbean <scp>S</scp>ea
Abstract Killer whales O rcinus orca are found in all oceans of the world, but most of our knowledge on the species comes from studies conducted at higher latitudes. Studies on killer whales in the C aribbean have been scarce. We compiled 176 records of killer whales from the C aribbean, including 9...
