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 water-holding frog has an aestivation cycle. It buries itself in sandy ground in a secreted, water-tight mucus cocoon during periods of hot, dry weather. Australian Aboriginals discovered a means to take advantage of this by digging up one of these frogs and squeezing it, causing the frog to empty its bladder. This dilute urine—up to half ...
A frog sitting on the handle of a saucepan on a hot stove. The frog in this photo was unharmed. [1] The boiling frog is an apologue describing a frog being slowly boiled alive. The premise is that if a frog is put suddenly into boiling water, it will jump out, but if the frog is put in tepid water which is then brought to a boil slowly, it will ...
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 ...

Water-holding frogs are ectothermic, [8] meaning they depend on external sources of body heat. Aestivation is a behaviour characteristic of water holding frogs. It is similar to how other animals hibernate, except it takes place during summer as opposed to winter when weather conditions are hot and dry. This behaviour is a response to high ...
Heat loss is a major threat to smaller creatures, as they have a larger ratio of surface area to volume. Small warm-blooded animals have insulation in the form of fur or feathers. Aquatic warm-blooded animals, such as seals, generally have deep layers of blubber under the skin and any pelage (fur) that they might have; both contribute to their ...
Such organisms (frogs, for example) rely on environmental heat sources, [3] which permit them to operate at very economical metabolic rates. [4] Some of these animals live in environments where temperatures are practically constant, as is typical of regions of the abyssal ocean and hence can be regarded as homeothermic ectotherms.
