Penguin

Penguins are flightless seabirds whose wings act as flippers for swimming. Dense feathers and streamlined bodies support life in water, where they hunt fish, squid or crustaceans. Most species live in the Southern Hemisphere, but their habitats range from icy coasts to much warmer shores. Penguins come ashore or onto ice to breed and molt. Parents share incubation and chick care in many species, though nesting methods differ. Their contrasting dark backs and pale fronts are recognizable above water and help reduce visibility from different directions at sea.
