It may or may not be reciprocal, and occurs in both endotherms and ectotherms. [1] One of its forms is huddling . However, kleptothermy can happen between different species that share the same habitat , and can also happen in pre-hatching life where embryos are able to detect thermal changes in the environment.
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 ...
The largest extant proboscidean is the African bush elephant, with a world record of size of 4 m (13.1 ft) at the shoulder and 10.4 t (11.5 short tons). [2] In addition to their enormous size, later proboscideans are distinguished by tusks and long, muscular trunks, which were less developed or absent in early proboscideans.
The descendants of the giant "hyracoids" (common ancestors to the hyraxes, elephants, and sirenians) evolved in different ways. Some became smaller, and evolved to become the modern hyrax family. Others appear to have taken to the water (perhaps like the modern capybara), ultimately giving rise to the elephant family and perhaps also the sirenians.
Behavioral thermoregulation takes precedence over physiological thermoregulation since necessary changes can be affected more quickly and physiological thermoregulation is limited in its capacity to respond to extreme temperatures. [34] When the core temperature falls, the blood supply to the skin is reduced by intense vasoconstriction. [18]
Key to maintaining homeostasis, individual thermoregulation is the ability to maintain internal body temperature in humans, the most recognizable eurytherm. In humans, deep-body temperature is regulated by cutaneous blood flow , which maintains this temperature despite changes in the external environment. [ 24 ]
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.
Different species have different temperatures of their thermal neutral zones. In dogs, the thermoneutral zone ranges from 20–30 °C (68–86 °F). [9] Domestic cats have a considerably higher thermoneutral zone, ranging between 30 and 38 °C.
