Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. 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
Warm-blooded animals could have gained an advantage by creating an inhospitable environment for many disease-causing organisms, thus reducing the risk of infections. Insulation and Thermoregulation: Homeothermy could have originated as a response to the development of insulating structures like fur, feathers, or other coverings. As animals ...
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.
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 ...
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. Endothermy requires plenty of food energy, so mammals eat more food per unit of body weight than most reptiles. [ 141 ]
Insulated, waterproof boots with adequate traction can keep feet warm and safe on icy terrain. The brands I use and recommend the most: Merrell, Sorel, Skechers. Hand and foot warmers.
Historically, the same word was used by de Candolle to describe plants that require a moderate degree of heat for successful growth. [5] In his scheme, a mesotherm plant grew in regions where the warmest month had a mean temperature greater than 22 °C (72 °F) and the coldest month had a mean temperature of at least 6 °C (43 °F).
