A thick layer of blubber and tightly-packed, oily feathers are ideal for colder temperatures. The 18 different species of penguins can widely in shape and size but all have black bodies and white bellies. This protective countershading allows them to hide from predators like leopard seals and orcas while they swim. While penguins can’t fly, their stiff flippers, webbed feet and sleek shape make them expert swimmers.
