The Defenders of Wildlife defines the penguin as a flightless bird that spends approximately 75 percent of its time in water. The tuxedo appearance exhibited by the bird is a type of camouflage known as countershading, and the coloring protects the bird as it swims.

Although the birds capture their food in the water, they raise baby penguins on the land. According to the Defenders of Wildlife, staples of the penguin diet include squid, fish and krill. Birds that live near the equator consume more fish, while Antarctic penguins generally eat more krill and squid.

The Defenders of Wildlife states that larger penguins live in colder environments, while smaller species live in warmer climates. The emperor penguin breeds in the coldest place on Earth. No other species of birds breed in such a frigid place. Temperatures in the Antarctic can be as low as 40 degrees below zero on the Fahrenheit scale, with winds reaching close to 90 miles per hour.
