WebJun 19, 2015 · Poikilothermic fish have no control over their body temperature and their core body temperature can fluctuate broadly. While some ectothermic stenotherms thermoregulate their body temperature by inhabiting constant temperature environments, internal temperature of poikilotherms can widely vary.

In fact, this response is produced by all the animals. Most of these proteins are synthesised just when a body temperature increase happens or by other factors. WebEctotherms usually live in environments in which temperatures are constant, such as the tropics or ocean. Ectotherms have developed several behavioral thermoregulation mechanisms, such as basking in the sun to increase body temperature or seeking shade to decrease body temperature. Endotherms
