What makes a fish want to live in the desert?
Did you know that there are fish living in the Australian desert? Obviously, fish need water, and that’s usually scarce in the desert. However large parts of arid Australia sit over the Great Artesian Basin, which is an area where groundwater is under such pressure that if you dig a well, it’ll come to the surface all by itself… no pumping required!

Because these springs are so isolated from other sources of fish, unique species have evolved that live only in spring complexes.
