Endothermy

Endothermy, colloquially referred to as warm-bloodedness, was the physiological ability of some creatures to control their body temperatures through metabolic means, notably by burning food within themselves. To keep a being's body temperature high even in cold weather, that process required that being to use more food. In hot weather, the body of an endothermic being had ways of cooling itself off through perspiration—a process which, at least in Humans, produced a distinct smell. The opposite of endothermy was ectothermy. All mammals,Alien Encounters including Humans and Krytollak,Galaxy Guide 12: Aliens — Enemies and Allies and most avians were warm-blooded lifeforms. While endothermic reptiles existed,The Essential Guide to Alien Species they were not overly common.
