Physiological adaptation to very dry condition in animals is called aestivation. Aestivation is a survival strategy used by animals in extremely hot and dry environments where water and food may be scarce. It involves the slowing down of metabolism, reduction of water loss, and the ability to remain inactive for long periods of time until environmental conditions improve. Aestivation is often seen in amphibians, reptiles, and some invertebrates such as snails and insects.
