Penguins are a species of flightless birds belonging to the order Sphenisciformes, and family Spheniscidae. They are characterized as flightless aquatic birds and are native to the southern hemisphere. The largest of their species being the Emperor penguin and smallest being The Little Blue Penguin.

They are known to feed on krill, fish, squid, and other forms of sea life caught while swimming underwater. They spend half of their life on land mostly during breeding seasons and half in the oceans.

The origin of the name penguin is not known but is believed to be from the name penguigo which was called the fat under the penguin's skin. Which brings up a theory that penguins were once killed for fat.

[edit] Structure

Penguins are very sturdily built aquatic swimmers. Their body, being shaped like a torpedo, helsp them literately 'fly' through the water at nearly 27 km/m (17 mph) and dive at least 6–12 km/h (3.7–7.5 mph). The smaller penguins usually never dive far, but emperor penguins have been recorded to reach a depth of 565 m (1,870 ft)
