These cute seabirds have wings, but they cannot fly. They wear a black or blue-grey overcoat, and they have a white belly, a pair of short legs, and two wings that serve as flippers (腳蹼). There are 18 types of them. We must look at their heads and necks to tell one type from another. Some have a pair of long, yellow eyebrows, some have a rock star hairstyle, some have lemon-yellow and orange markings on their cheeks (臉頰), and some just have no special markings at all. When these seabirds walk on land, they look clumsy (笨拙的). Yet, when they dive into the water, they become excellent swimmers! Most of them live in places covered by snow and ice year-round in the Southern Hemisphere, but some are found in warmer areas near the equator (赤道). What are they? These cute seabirds are penguins!
King penguins and emperor penguins are the two largest types of penguins. King penguins can reach a height of 38 inches, and emperor penguins can be 48 inches tall. The smallest penguin is the little blue penguin from Australia and New Zealand—when it stands straight, it is just about 16 inches tall. Big penguins have some advantages over their smaller relatives—big penguins can stay warm easier so they can live in a colder climate; big penguins can dive deeper and stay underwater longer so they can catch food far below the water surface.
