WebPoikilothermic animals have developed characteristic behaviours which allow them to regulate their own body temperature. Salamanders for example bask in the morning sunshine in order to reach “operational temperature” while many flying insects warm up by means of rapid contractions of their wing muscles. Privacy settings WebExamples of poikilotherms include the "cold-blooded" animals (Kearney et al. 2009), such as most fish, amphibians, and reptiles. On the other hand, homeotherms have specific …

WebSep 13, 2024 · Poikilotherms are animals that cannot maintain a constant body temperature and instead rely on the external environment to regulate their internal temperature. These animals are often ectotherms, meaning they rely on external sources of heat to raise their body temperature. WebInsectshave 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 regardless of external influences).
