The emperor penguin is one of only two penguin species that live on the frozen Antarctic continent. Penguin is the common name for 17 species of flightless seabirds widely distributed in cooler waters and along coastlines in the Southern Hemisphere. Skilled swimmers, penguins have streamlined, barrel-like bodies that reduce drag in the water. Their wings, modified to form thin, stiff flippers, provide propulsion while swimming.
Unlike the bones of other birds, penguin bones are solid, not hollow, which helps them remain submerged underwater. On land, penguins have a waddling gait due to their short, thick legs set far back on the body. Penguins come ashore to breed, but they are, in fact, true marine animals, spending as much as 80 percent of their lives underwater.
Studies indicate that penguins are champion divers. The large emperor penguin can reach depths of over 1,600 ft (500 m).
While most birds shed their feathers and grow new ones during a relatively long period of the year, penguins renew their entire plumage over two to four weeks.
A molting penguin generally stands immobile during its molting period, and has a very swollen, disheveled appearance.
