Warm-blooded. Warm-blooded is an informal 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. Other species have various degrees of thermoregulation .
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.

Homeothermy. 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. This internal body temperature is often, though not necessarily, higher ...
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.
After Hamilton had plastic surgery on his eyes — what humans would call a nip and tuck — he was able to see and interact with his owners with no pain. “These nip and tucks are not cosmetic ...
The trio are accused of moving out of a home on Emerson Drive and leaving behind two dogs intentionally confined in crates without food or water. One of the dogs died while the other survived ...
Thermoregulation. Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Researchers say they've discovered the first known fully warm-blooded fish. It's called the opah, or moonfish, and it lives in cold environments deep below the ocean's surface. Scientists say the ...
