  2. Ectotherm - Wikipedia

    en.wikipedia.org/wiki/Ectotherm

    In addition to behavioral adaptations, physiological adaptations help ectotherms regulate temperature. Diving reptiles conserve heat by heat exchange mechanisms, whereby cold blood from the skin picks up heat from blood moving outward from the body core, re-using and thereby conserving some of the heat that otherwise would have been wasted. The ...

  3. Temperature-size rule - Wikipedia

    en.wikipedia.org/wiki/Temperature-size_rule

    Environmental temperature is one of the most important proximate factors affecting ectotherm body size because of their need to thermoregulate. Individuals that have been observed to follow the temperature-size rule have slower growth rates in colder environments, yet they enter a period of prolonged growth that yields larger adult body sizes.

  4. Gigantothermy - Wikipedia

    en.wikipedia.org/wiki/Gigantothermy

    Gigantothermy (sometimes called ectothermic homeothermy or inertial homeothermy) is a phenomenon with significance in biology and paleontology, whereby large, bulky ectothermic animals are more easily able to maintain a constant, relatively high body temperature than smaller animals by virtue of their smaller surface-area-to-volume ratio. [1]

  5. Insect thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Insect_thermoregulation

    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 ...

  6. Warm-blooded - Wikipedia

    en.wikipedia.org/wiki/Warm-blooded

    Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment.

  7. Thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Thermoregulation

    Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.

  8. Physiology of dinosaurs - Wikipedia

    en.wikipedia.org/wiki/Physiology_of_dinosaurs

    Many bipedal dinosaurs possessed gracile leg bones with a short thigh relative to calf length. This is generally an adaptation to frequent sustained running, characteristic of endotherms which, unlike ectotherms, are capable of producing sufficient energy to stave off the onset of anaerobic metabolism in the muscle. [91]

  9. Sunning (behaviour) - Wikipedia

    en.wikipedia.org/wiki/Sunning_(behaviour)

    A grey heron in delta-wing posture, facing the Sun. Sunning or basking, sometimes also known as sunbathing, is a thermoregulatory or comfort behaviour used by humans, animals, especially birds, reptiles, and insects, to help raise their body temperature, reduce the energy needed for temperature maintenance or to provide comfort.
