Do Poikilotherms Regulate Body Temperature?

Behavioral thermoregulation in poikilotherms can result in sustained average body temperatures that are optimal for crucial metabolic activities, such as feeding and locomotion (Huey & Kingsolver 1989).

Can poikilotherms regulate body temperature?

Homeotherms maintain their body temperature within a narrow range, while poikilotherms can tolerate a wide variation in internal body temperature, usually because of environmental variation. Heat can be exchanged between environment and animals via radiation, evaporation, convection, or conduction processes.

Do poikilotherms have homeostasis?

A poikilotherm is an organism whose internal temperature varies considerably. It is the opposite of a homeotherm, an organism which maintains thermal homeostasis. Poikilotherm's internal temperature usually varies with the ambient environmental temperature, and many terrestrial ectotherms are poikilothermic.
