Penguins – An Introduction
Saturday, October 7th, 2006Penguins are aquatic flightless birds. There are approximately 16 to 19 species of penguins known until now. All penguins have a white underside and a dark (mostly black) upper side, the white side acts as a camouflage for predators in the water and the dark plumage on their backs camouflages them from above. Penguins feed on krill, squid, fish and other sea life forms while swimming underwater. Half of their lives are spent in the ocean and half on land.
