A cold blooded animal, or ectotherm, is one that does not have an internal mechanism for regulating its body temperature. Instead, a cold blooded animal relies on solar energy captured by the environment. Reptiles, amphibians and fish are examples of cold blooded animals. Reptiles. Reptiles will often sun themselves on rocks to absorb heat.
Insects, worms, fish, amphibians, and reptiles fall into this category—all creatures except mammals and birds. The term cold-blooded is a little misleading because poikilotherms can have very warm body temperatures in the tropics. Cold-blooded actually means the animal’s body temperature is basically the same as its surroundings.
Cold-blooded animals or ectotherms are animals that lack an internal physiological mechanism to regulate their body temperature and thus, rely on the temperature of their surroundings for the same. Most of these species are found in areas where the temperature is more or less stable.
On the basis of regulation of body temperature, all animals are categorized into two groups. Mammals and birds are generally warm-blooded animals, whereas fish and reptiles are cold-blooded animals. This post provides you with a detailed comparison of these two categories of animals.
It is almost as if the warm-blooded animal becomes cold-blooded, as its body temperature drops considerably. But they are still alive, and they live off their fat reserves. Hibernation for extended periods of time is only accomplished by those animals that can store a great deal of body fat, such as bears, groundhogs, and chipmunks.
COLD-BLOODED ANIMALS Cold-blooded animals do not have cold blood. Instead, their body temperature changes as the temperature around them changes. Fish, amphibians and reptiles are all cold-blooded. Scientists call this trait ectothermy, from ecto which means outside, and therm, which means heat.
Cold-blooded animals like lizards, insects and fish have a preferred body temperature range at which they hunt, eat, move quickly and reproduce. Fear that a warming climate will constrict this ...

Total area within each section means a wider lethal temperature range across all acclimation temperatures.
Warm-blooded animals can remain active, seek food, and defend themselves in a wide range of outdoor temperatures. Cold-blooded animals can only do this when they are warm enough. A cold-blooded animal's level of activity depends upon the temperature of its surroundings.
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "hot"), is an organism in which internal physiological sources of heat are of relatively small or quite negligible importance in controlling body temperature. Such organisms (for example frogs) rely on environmental heat sources, which permit them to operate at very economical metabolic rates.
