What is endothermic metabolism?
endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. If heat loss exceeds heat generation, metabolism increases to make up the loss or the animal shivers to raise its body temperature.
What it means to be warm-blooded?
Definition of warm-blooded 1 : having warm blood specifically : having a relatively high and constant internally regulated body temperature relatively independent of the surroundings. 2 : fervent or ardent in spirit. Other Words from warm-blooded Synonyms & Antonyms Learn More About warm-blooded.
What is the definition of a cold-blooded animal?
Animals, such as reptiles, fishes, and amphibians, that cannot control their body temperature and therefore become sluggish in cold weather. (Compare warm-blooded animals.)
What is an ectothermic animal?
ectotherm, any so-called cold-blooded animal—that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
What do you mean by Endothermy?
Endothermy can be defined as any mechanism of heat generation without shivering that increases body temperature and resting metabolic rate.
What is regional Endothermy?
Regional endothermy is the ability of some fish lineages to maintain certain body areas at higher temperatures than the surrounding water by means of vascular countercurrent heat exchangers or specialized thermogenic organs [17,18].
Do cold blooded humans exist?
So NO, PHYSICALLY THERE HAS NEVER BEEN A COLD BLOODED HUMAN BEING…. …. however, PSYCHOLOGICALLY, the phrase “cold-blooded” can mean someone who is uncaring, unfeeling or cruel, who is capable of extreme violence onto others while feeling no remorse.

What’s the difference between warm and cold blooded animals?
Cold-blooded animals can be defined as animals that cannot regulate their internal body temperature with the change in the environment.

What animals are regulators?
Birds and mammals regulate their body temperatures and can live in large ecological niches. These kinds of animals are called regulators, or homeotherms. Conformers, or poikilotherms, must relocate to maintain body temperature. Lizards, insects and fish represent examples of conformers.
