Their impressive size and fierce hunting skills have earned killer whales the title of “top predator of the ocean.” Their distinctive black and white coloration — disruptive coloration — may enhance their hunting abilities. This type of color pattern contradicts the killer whale’s body shape and in the flickering filtering sunlight of the sea, other animals may not recognize a killer whale as a potential predator. Their diets vary from one region to another, but mostly consist of fishes, squids, seabirds (including penguins), and marine mammals.
