Aestivation



![Aestivation has been put forward as the most likely explanation why this therapsid cynodont Thrinaxodon liorhinus shared its burrow with a temnospondyl amphibian, Broomistega putterilli.[6]](/uploads/202412/20/-Synchrotron-Reveals-Early-Triassic-Odd-Couple-Injured-Amphibian-and-Aestivating-Therapsid-Share-pone.0064978.s001.ogv1551.jpg)
Aestivation or æstivation (from Latin:aestas, summer, but also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months.
