Hello TheOldSchool, i think the biggest and heavy Animal that ever live on this earth is : Bruhathkayosaurus
Dalia, I am not at all certain where this is all headed, but please, feel free to continue. Kinda sounds like "Poikilotherms" might be associated with the human species with reference to the "time, location and situation". I mention this because when engaged in certain activities the human species can easily overheat, even when it is in a colder environment. Like wise in an oppressively hot situation a human can develop "cold feet', so to speak.Hello TheOldSchool, i think the biggest and heavy Animal that ever live on this earth is : Bruhathkayosaurus

They could be so big and heavy because they were :
Poikilotherms (or "cool" or pœcilotherme) are animals with a body temperature that varies with that of their environment. By this characteristic, they differ and are opposed to warm-blooded animals which have a relatively stable internal temperature. They are not to be confused with heterotherms that are warm-blooded which usually steady body temperature varies in some cases (hibernating animals, infants whose body temperature is not stable yet, etc.)
Most cold-blooded organisms (that do not control their body temperature) are ectothermic (that is to say, their body heat comes from outside). However, there are special cases, and it is necessary to recall that ectothermic poikilothermic and are not synonymous.
This lack of control of the internal temperature prevents a "normal" activity during cold periods, but it is a much more economical characteristic energy homeotherms. Both have survived because they are characteristic of different lifestyles, even if we consider that homeothermy is an evolving character.
would you call birds and alligators modern dinosaurs?Hello I amao IR,
Poikilothermic animals include types of vertebrate animals, specifically fish, amphibians, and reptiles, as well as a large number of invertebrate animals. The the naked mote- rat is the only mammal that is currently thought to be poikilothermic.
