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.

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 ...
In general, warm-bloodedness refers to three separate categories of thermoregulation.. Endothermy [a] is the ability of some creatures to control their body temperatures through internal means such as muscle shivering or increasing their metabolism.
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.
During these multi-day torpor bouts, body temperature drops to ~1 °C above ambient temperature and metabolism may drop to about 1% of the normal endothermic metabolic rate. Even in these deep hibernators, the long periods of torpor is interrupted by bouts of endothermic metabolism, called arousals (typically lasting between 4–20 hours).
[1] The light which constitutes the cosmic microwave background comes from the surface of last scattering. This is, on average, the surface at which primordial photons last interacted with matter in the universe , or in other words, the point at which photons started free streaming. [ 2 ]
