Best Answer

There are a few species of fish that have evolved in places where the water supply is not always reliable and so they have developed different methods of surviving. The vast majority of small fish like the Australian Rainbow Fish that have evolved under these wet and dry conditions spawn as soon as the water starts to get shallower and then die in the drought. Once the wet (rains) come the ova hatch and the fish are back. Others like the Australian Lungfish have developed a form of lung that they can use when theyhave to survive in the mud (almost hibernating) until the rain comes and the rivers flow again. Still others that evolved where the pools do not completely dry out have to live in very oxygen depleted water. These species have developed 'labyrinths' in which small quantities of air can be gulped. The Gouramies and Bettas do this.
