Penguins are flightless seabirds that live almost exclusively below the
equator. Some island-dwellers can be found in warmer climates, but
mostāincluding Emperor, AdĆ©lie, Chinstrap, and Gentoo penguinsāreside in and
around icy Antarctica. 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 canāt fly, their stiff flippers, webbed feet, and sleek shape
make them expert swimmers. In fact, they spend most of their lives in the
ocean and do nearly all of their hunting for krill, squid, and crabs
underwater.
They can swim about 15 miles an hour, and when they want to go faster,
they often porpoise, or leap out of the water as they swim.
