An ectotherm (from Ancient 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.

Jan 28, 2020 · Ectotherm Definition. An ectotherm is an organism which derives the heat it requires from the environment. This is in contrast to an endotherm, which creates the heat it needs from internal chemical reactions. A common misconception is …

Mar 25, 2024 · Ectotherms regulate body temperature through external sources, while poikilotherms have variable body temperatures dependent on environmental conditions. Ectotherms are organisms that rely on external environmental conditions to …

Jan 16, 2025 · Ectotherms, organisms that rely on external sources to regulate their body temperature, offer a fascinating study in adaptation and survival. These creatures, including reptiles, amphibians, and fish, have evolved various strategies to thrive in environments with fluctuating temperatures.

Ectotherm (adj. ectothermic) An organism whose body temperature is largely determined by heat exchange with its surroundings. It does not produce and retain enough metabolic heat to elevate its body temperature above ambient temperature, but may use behavioral mechanisms to regulate body temperature
