We think of fish as completely aquatic animals. But there are actually hundreds of fish species that are amphibious, meaning that they possess adaptations that enable them to survive on land. Once on land, however, they face suffocation, drying up, and being hunted by land predators. So why do fish make the exodus from water to land?

我们认为鱼是完全水生的动物。但实际上，有数百种鱼类是两栖动物，这意味着它们拥有使它们能够在陆地上生存的适应性。然而，一旦到了陆地上，它们就会面临窒息、干涸和被陆地上的捕食者猎杀。那么，为什么鱼会从水中逃到陆地上呢？
