All penguins have the well known tux coloration. All but one of the living species are birds of the cold seas of the Southern hemisphere. The other specie lives on the Galapious Islands on the Equator. Penguins evolved from the same ancestral stock as the Albatrosses, supreme masters of flight. Guess the Albatrosses won the coin toss.
Penguins litually fly through the water using their fleshy feet as ruders.
Actually Penguins can't fly, but that is because they are too short to reach the ticket box at the airline. Some birds will gradually loose feathers while new ones grow in under them. Not the penguin though Penguins grow new feathers under the old ones and the old ones are shed simultaneously. However, it can be very embarrassing at cocktail parties. Penguins are warm blooded.
