Penguins

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