About Penguins


Penguins orderSphenisciformes, familySpheniscidae) are a group of aquatic, flightlessbirds living almost exclusively in the Southern Hemisphere, especially in Antarctica. Highly adapted for life in the water, penguins havecountershaded dark and white plumage, and their wings have evolved into flippers. Most penguins feed on krill, fish, squid and other forms of sealife caught while swimming underwater. They spend about half of their lives on land and half in the oceans.
