Australia's arid interior is a land of stark beauty. Stretching for over two million square miles, it's a vast mosaic of red sand dunes, mulga woodlands, dry flood plains, and spinifex grasslands. Occupying this land of extremes are hosts of desert nomads, water seekers, and ferocious carnivores. They come in a variety of shapes, sizes, and species but share one similarity: remarkable adaptations that have allowed them to survive, and even thrive in this world of boom or bust, which has been reshaped by colossal forces over millions of years.
