Mammals have warm blood. The important thing about mammals and birds is that they maintain a constant internal temperature. They have a heavy covering on their body in the form of wings and also. Warm bloodedness a characteristic of mammals is a trait encompassing a suite of physiological processes that helps to maintain a relatively high constant body temperature.
Some mammals are classed as heterothermic allowing their surrounding environments to affect their self regulating body temperature. Still they are endothermic. The only known living homeotherms are birds and mammals though ichthyosaurs pterosaurs plesiosaurs and non avian dinosaurs are believed to have been homeotherms.
We are taught that all mammals have warm blood but in fact there are a few exceptions to this rulewhen bbc earth went onto facebook and asked our audience if there are any cold blooded mammals. Time to bust a myth. In particular homeothermic species maintain a stable body temperature by regulating metabolic processes.
These animals live in oceans and seas and are susceptible to cold temperatures. However warm blood is not really the question many reptiles have blood far warmer than ours but only on hot days. In fact blood temperature is merely a reflection of body temperature.
For example whales seals and dolphins also have warm blood with the body temperature of 37 c. Warm blooded are those animal species which can maintain a body temperature higher than their environment. Not all mammals are warm blooded we are taught that all mammals have warm blood but in fact there are a few exceptions to this rule share on facebook.
