Despite these limitations, frogs are widespread, and have adapted to many climates, even deserts. They rely on specific adaptations to survive. Members of the genus "Cyclorana" live in the Australian central desert. They bury themselves underground where they create a waterproof cocoon in which to aestivate during dry periods. Once it rains, they come out, find a temporary pool, and breed. Egg and tadpole development is very fast in comparison to those of most other frogs, so breeding can be completed before the pond dries up.
