An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
Cold-blooded is an informal term for one or more of a group of characteristics that determine an animal's thermophysiology. These include: These include: Ectothermy , controlling body temperature through external processes, such as by basking in the sun
Amphibians are ectothermic (cold-blooded) vertebrates that do not maintain their body temperature through internal physiological processes. Their metabolic rate is low and as a result, their food and energy requirements are limited. In the adult state, they have tear ducts and movable eyelids, and most species have ears that can detect airborne ...
“Warm-blooded animals are generally more active, for example, cold-blooded animals usually don’t build nests,” said lead study author Dr. Alfio Alessandro Chiarenza, Royal Society Newton ...
The naked mole-rat exhibits a highly unusual set of physiological and behavioral traits that allow it to thrive in a harsh underground environment; most notably its being the only mammalian thermoconformer with an almost entirely ectothermic (cold-blooded) form of body temperature regulation, [8] as well as exhibiting a complex social structure ...
Turtles are ectotherms or "cold-blooded", meaning that their internal temperature varies with their direct environment. They are generally opportunistic omnivores and mainly feed on plants and animals with limited movements.
Most sharks are "cold-blooded" or, more precisely, poikilothermic, meaning that their internal body temperature matches that of their ambient environment. Members of the family Lamnidae (such as the shortfin mako shark and the great white shark ) are homeothermic and maintain a higher body temperature than the surrounding water.
Osteichthyes are primitively ectothermic (cold blooded), meaning that their body temperature is dependent on that of the water. But some of the larger marine osteichthyids, such as the opah , [ 19 ] [ 20 ] swordfish [ 21 ] [ 22 ] and tuna [ 23 ] have independently evolved various levels of endothermy .
