ectothermAny 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. The body temperatures of aquatic ectotherms are usually very close to those of the water. Ectotherms do not require as much food as warm-blooded animals (endotherms) of the same size, but most cannot deal as well with cold surroundings. ectotherm [′ek·tə‚thərm] (physiology) An animal that obtains most of its heat from the environment and therefore has a body temperature very close to that of its environment.

No references found | These animals are ectotherms and sunbathe to regulate their body temperature. Tropical species are affected more by the very narrow temperature range of their typically warm climate than are ectotherms living where the temperatures fluctuate in greater degrees. The mass specific standard respiration rate (MSR) is a measure of the intensity of basal aerobic metabolism and is primarily controlled by the habitat temperature in ectotherms. |
