A penguin not only wears a white shirt and a black jacket, but also has a smart yellow tie! Maybe because of this, there are many stories about penguins. However, many of these stories are not right. For example, some penguins in the stories live in the Arctic Circle (北极圈). In real life, there are no wild penguins in the northern hemisphere (北半球).
There are about twenty different kinds of penguins in the world. Penguins usually live not only on land, but on snow and ice as well. In fact, many penguins spend most of their lives staying in the sea. And most penguins like to live in open water with no ice.
Do penguins sing songs? It is known that there are three kinds of penguin songs. They talk with each other by singing songs. But most of them don’t talk all the time because talking cuts down energy. So we often see penguins in small groups walking freely, or quietly resting on the beach in the sun.
