Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals ) maintain a stable body temperature by regulating metabolic processes.
The group that includes mammals and birds, both "warm-blooded" homeothermic animals (in red) is polyphyletic. Homeothermy, homothermy or homoiothermy [1] is thermoregulation that maintains a stable internal body temperature regardless of external influence.
Nearly all mammals are endothermic ("warm-blooded"). Most mammals also have hair to help keep them warm. Like birds, mammals can forage or hunt in weather and climates too cold for ectothermic ("cold-blooded") reptiles and insects.
Mammals and birds are warm-blooded. A snake was found in a Woodbridge garage in Bluffton on Monday night. For a better understanding, “cold-blooded actually means the animal’s body temperature ...
Unlike mammals and birds, some reptiles, particularly some species of python and tegu, possess seasonal reproductive endothermy in which they are endothermic only during their reproductive season. In common parlance, endotherms are characterized as "warm-blooded".
They are warm-blooded, i.e., they hold a nearly constant body temperature. [37] ... As with all mammals, the oxygen is stored in the blood and the lungs, but in ...
Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found.
A recent study has determined that dinosaurs may have been warm-blooded based on a re-assessment of previous research on animals? growth and metabolic rates.
