There was a lot of noisy debate of this question, both in scientific literature and the popular media, during the 1990s. While is it no longer so frequently discussed, the question is still not conclusively resolved. The truth is, we really don't have enough knowledge of dinosaur physiology to be certain. It is quite possible that they were not really warmblooded (endotherms), but they could regulate their body temperature quite a lot more than modern reptiles. Also, the term "dinosaur" covers an enormous variety of species, that existed at different times in geologic history, under different conditions. While it is plausible that some dinosaurs were warmblooded, it is extremely unlikely that all of them were, so the only reasonable answer, given our current knowledge, is "many dinosaurs were ectotherms".
Reptiles (Lizards and Snakes) are ectotherms Amphibians are ectotherms
Ectotherms their body temperature changes with the environment
Endotherms are warmblooded, ectotherms are coldblooded, so amphibians are ectotherms.
Yes. As a rule of thumb; all animals are ectotherms except for mammals and birds.
No, they were not. There were many other warm blooded species before them. I'm not sure of specific names, but I know that birds were along much longer than the dinosaurs, and birds are warm blooded. Let me clarify from above. According to the currently accepted Evolution Theory, birds evolved from dinosaurs. Birds are warm blooded but dinosaurs, as far as the scientists can tell, were cold blooded.
ectotherms' body temperature change with surrounding climate. hence to avoid exposure to cool temperatures, they hibernate.
endothermic
They are endotherms
Endotherm.
All mammals are endothermic (warm blooded). Ectotherms are cold blooded animals like snakes and lizards.
A squid is ectotherm. Any animal except birds and mammals are ectotherms
no its not, ectotherms are cold-blooded
