WebMay 28, 2013 · Fish are poikilothermic organisms, or in simpler terms, cold-blooded animals, which means that the lower the temperature of their surroundings is, the harder it is for them to maintain their metabolic functions. Furthermore, as temperatures go lower, ice crystals can form in the organism’s cells and thus the animal might suffer irreversible ... WebPoikilotherms: An animal that regulates its internal body temperature throughout a wide range of temperatures, frequently in response to changes in the ambient temperature is known as poikilotherms. "Ectotherms" or "cold-blooded creatures" are alternate terms for poikilotherms. A minor change in body temperature has little effect on poikilotherms. party of the first part
