Australia: The Land Where Time Began

A biography of the Australian continent 

This is small fish is supremely adapted to the erratic, highly variable conditions of the arid Australian inland, where it is endemic. The range of environmental conditions it can survive in is a list of the environmental problems facing fish in the arid zone. It can not only live in fresh water, but even in distilled water, but can also live in saline water with salt concentrations as high as sea water, a temperature range of 5-40^o C, finding the cooler layers in warm pools, and staying in side shallows that are cooler, or burying itself in the cooler sediments. It can also emerge from the water to cool down by evaporation. In almost stagnant water it stays on photosynthesising algal mats where the dissolved oxygen is highest, and oxygen bubbles rise to the surface.
