This is a type of dormancy which is very much like hibernation. It is described as reduced metabolic rate and inactivity in response to dry conditions and high temperatures. Both invertebrates and vertebrates have the ability to enter into this state to avoid exsiccation. Critters undergoing aestivation appear as though they are in a lighter state of dormancy, since they are able to reverse their physiological state quickly and come back to “normal”. Crocodiles, desert tortoises, desert toads, and salamanders are just a few examples of creatures that aestivate.
