MOST birds are built for life in the air, but penguins are far better equipped for life in the water.
These flightless birds use their wings as paddles when they are swimming, enabling them to "fly" through the water.
Some penguins travel at a speed more than 35kmh when swimming underwater, making them the fastest swimming birds on earth.
Penguins eat fish and shellfish.
They normally raise their young in "families", with adults caring for a number of young rather than just their own. - bigsiteofamazingfacts.com
