Did you ever hear of a fish that can live for a long time without being in water?
The lungfish(肺鱼)breathes through gills just as other fish do. But unlike other fish, it also has lungs. So the lungfish can breathe air just as animals living on land do. For this reason, a lungfish can live for a long time without being in water.
Most lungfish live in Africa, where they are found in shallow lakes and rivers. Sometimes, very little rain falls. Then, the shallow lakes and rivers dry up, and the other fish in the river die. What happens to a lungfish? It curls up into a ball in the mud at the bottom of the lake or river. Then, it be gins to breathe with its lungs instead of its gills.
If necessary, a lungfish can live this way for as long as three or fouur years. When the rains come, the lungfish straightens itself out. And it begins swimming around in the water again－almost as if nothing had happened!
