Reptiles have only an extremely limited mechanism to control their own body heat. Because of this, their body heat is affected more by the external temperature. Where a mammal has many ways to preserve body heat (raising the hair, constricting blood vessels close to the skin, shivering), a reptile will lose heat to a colder environment. Ectothermic is the name for these organisms, who are also known as being 'cold blooded'.

∙ 8y agoAn ectotherm, from the Greek εκτός (ektós) "outside" and θερμός (thermós) "hot", refers to organisms that control body temperature through external means. As a result, organisms are dependent on environmental heat sources[1] and have relatively low metabolic rates.[2] For example, many reptiles regulate their body temperature by basking in the sun. The opposite of ectothermy isendothermy, where heat is primarily generated as a result of internal metabolic processes. Many ectotherms are also poikilotherms, meaning their temperature varies over a wider range thanhomeotherms.

Reptiles
Are reptiles endothermic or ectothermic?
They are Ectothermic. They require an external heat source to raise their body temperature. Unlike mammals - which generate their own heat.
