Feb 5, 2013 · They just do not SPEND energy specifically on heating their bodies by raising their metabolisms. This is a form of energy conservation. The metabolic rate they need to live is not nearly enough to heat their bodies. An example of spending energy to heat the body is seen in humans shivering.
Mar 5, 2024 · The temperature of cold blooded or ectothermic animals varies with the environment, while warm blooded or endothermic animals maintain a relatively stable temperature. The animal kingdom falls into two categories based on how species regulate their body temperature : ectothermic and endothermic.
Cold-blooded animals do not maintain a constant body temperature. They get their heat from the outside environment, so their body temperature fluctuates, based on external temperatures. If it is 50 °F outside, their body temperature will eventually drop to 50 °F, as well.
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]
ectotherm, any so-called cold-blooded animal —that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.

Oct 31, 2023 · Ectotherms use external sources of temperature to regulate their body temperatures. Ectotherms are colloquially referred to as “cold-blooded” even though their body temperatures often stay within the same temperature ranges as warm-blooded animals.
