(noun) A flightless seabird of the southern oceans, well adapted to Antarctic waters with its short legs, thick, insulating feathers and hefty stores of body fat. Penguins are powerful swimmers and use their flipper-like wings to propel themselves at great speeds in pursuit of fish.
While penguins are often associated only with ice and cold, several penguin species actually breed in tropical regions in large colonies in breeding sites that will be used for generations. All penguins are found only in the southern hemisphere, though they are popular guests in aquariums throughout the world.
