Penguins (order Sphenisciformes — family Spheniscidae) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere, with only one species, the Galapagos penguin, found north of the equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Adult penguins only recognize their own baby chicks. Parents can tell the chicks apart based on a unique call that every chick has, according to SeaWorld.
