Aestivation occurs in animals living in deserts and tropical regions. This is done to protect themselves from hot and dry climate, and due to the scarcity of food water. This can be seen in earthworms, molluscs, arthropods, reptiles and amphibians.

Aestivation or estivation is the positional arrangement of the parts of a flower within a flower bud before it has opened. Aestivation is also sometimes referred to as praefoliation or prefoliation, but these terms may also mean vernation: the arrangement of leaves within a vegetative bud.
