Penguin Facts

Penguins are one of about 40 species of flightless birds, a category that also includes the ostrich, emu and kiwi. Penguins are neither the smallest nor the largest of the lot, but some may think of them as the most interesting.

These waddling birds are known for their white bellies and dark-colored backs and wings, resembling a tuxedo. This distinct coloring is thought to hide penguins from predators in the sea. Besides its coloring, a penguin’s body is designed for swimming, and includes tapering at both ends of the body for hydrodynamics, paddle-like wings and web-shaped feet.
