The common frog is a poikilotherm and is able to function over a wide range of body core temperatures. A poikilotherm (/ ˈ p ɔɪ k ə l ə ˌ θ ɜːr m, p ɔɪ ˈ k ɪ l ə ˌ θ ɜːr m /) is an animal (Greek poikilos – 'various', 'spotted', and therme – 'heat') whose internal temperature varies considerably.

Various aged naked mole-rats. The naked mole-rat (Heterocephalus glaber), also known as the sand puppy, [6] is a burrowing rodent native to the Horn of Africa and parts of Kenya, notably in Somali regions. [1]
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
English: Body temperature poikilotherm (green line) changes with ambient temperature, while homeotherm (blue line) regulates its own body temperature which remains constant regardless of ambient temperature (red line). All organisms must thermoregulate in some way.
Heterothermy or heterothermia (from Greek ἕτερος heteros "other" and θέρμη thermē "heat") is a physiological term for animals that vary between self-regulating their body temperature, and allowing the surrounding environment to affect it.
A creature with a fairly constant body temperature can therefore specialize in enzymes which are efficient at that particular temperature. A poikilotherm must either operate well below optimum efficiency most of the time, migrate, hibernate or expend extra resources producing a wider range of enzymes to cover the wider range of body temperatures.
A plot illustrating the dependence on temperature of the rates of chemical reactions and various biological processes, for several different Q 10 temperature coefficients. . The rate ratio at a temperature increase of 10 degrees (marked by points) is equal to the Q 10 coefficie
