Ectotherms use external sources of temperature to regulate their body temperatures. They are colloquially referred to as cold-blooded despite the fact that body temperatures often stay within the same temperature ranges as warm-blooded animals. Ectotherms are the opposite of endotherms when it comes to regulating internal temperatures.
The green crab is an exceedingly common species of shore crab. Considered an invasive species, the green crab's ability to function in a wide range of water and air temperatures allows it to vary widely in its range. The sustained supply of oxygen to body tissues determines the body temperature range of an organism.
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
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. [10] In horses, the lower critical temperature is 5 °C while the upper critical temperature depends on the definition used. [11]
Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes. Other species have various degrees of 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 ...
Because many homeothermic animals use enzymes that are specialized for a narrow range of body temperatures, hypothermia rapidly leads to torpor and then death. Additionally, homeothermy obtained from endothermy is a high energy strategy [ 5 ] and many environments will offer lower carrying capacity to these organisms.
A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). [ 1 ] [ 2 ] Many thermophiles are archaea , though some of them are bacteria and fungi .
