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.
Cold blooded is a generic term meaning a heavy boned even-tempered horse breed from Northern Europe such as a Shire, Clydesdale or other draft horse breed. "Cold" is from the climate of their origin, and does not mean a cold-blooded animal. [1]: 112 [2]: 47 Hot blooded is a generic term meaning a high-spirited horse, generally of Arabian or ...
While the ideal horse for registration is already a warmblood type, there are no breed restrictions for American Warmbloods. Horses which are 100% hot or cold blooded are not typical, but can be registered if they are able to meet the registry's performance standards (this would include draft horses, Arabians, and Thoroughbreds).

In reality, horses of all breeds are warm-blooded mammals and have the same body temperature. The notion of a "hot-blooded" horse is nevertheless taken up in later hippological writings, and remains in use today. Hot-blooded horses are saddle and sport animals, known for their liveliness, finesse, and emotional nature.
Small warm-blooded animals have insulation in the form of fur or feathers. Aquatic warm-blooded animals, such as seals, generally have deep layers of blubber under the skin and any pelage (fur) that they might have; both contribute to their insulation. Penguins have both feathers and blubber. Penguin feathers are scale-like and serve both for ...
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.
Strictly speaking, the term "warm blood" refers to any cross between cold-blooded and hot-blooded breeds. [115] Examples include breeds such as the Irish Draught or the Cleveland Bay. The term was once used to refer to breeds of light riding horse other than Thoroughbreds or Arabians, such as the Morgan horse. [104]
If predators were cold-blooded while their prey were warm-blooded, the predators might have struggled to hunt efficiently in cooler conditions. Homeothermy in prey species could have provided a competitive advantage by allowing them to maintain consistent performance across a wider range of temperatures.
