One reason might be the 'false economy' of having to heat up their bodies. Approximately 80% of human energy goes towards heating our bodies to a stable temperature. However, for fish and reptiles to do this, it may not have been a evolutionary advantage. For example snakes and crocodiles can gorge themselves on one large meal and then not have to feed again for months. This would not be possible if they had a 'central heating system'. Likewise fish would need to devote large amounts of energy towards heating up their bodies in colder water and it makes sense for them to merely adapt to it instead. An example of this is the fact that although fish are exothermic, many species are capable of surviving in large temperature variations (so long as they are not too rapid) that would quickly kill most mammals. Therefore although mammals are warm blooded, they are far less tolerant of changes in temperature that deviate too far from whatever their species ideal is.

Are wolfs cold blooded?
No a wolf is not a cold blooded animal. Wolves are mammals and they are warm-blooded. A warm blooded animal Will have a body temperature that is higher than its surrounding environment. Warm blooded animals are mainly mammals and birds. The wolf would not be a cold blooded animal. Cold blooded animals have a body temperature which reflects the environmental temperature. Cold blooded animals are mainly invertebrates, Fish, reptiles and amphibians.
