  2. Endotherm - Wikipedia

    en.wikipedia.org/wiki/Endotherm

    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 ...

  3. Warm-blooded - Wikipedia

    en.wikipedia.org/wiki/Warm-blooded

    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

  4. Homeothermy - Wikipedia

    en.wikipedia.org/wiki/Homeothermy

    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.

    In warm blooded animals (mammals and birds) this state is referred to as hibernation or torpor (shorter periods of inactivity between awakening); whereas a similar condition in cold-blooded ...

    Warm-blooded creatures — including birds, who are descended from dinosaurs, and humans — keep their body temperature constant whether the world around them runs cold or hot.

  7. Mammal - Wikipedia

    en.wikipedia.org/wiki/Mammal

    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. Endothermy requires plenty of food energy, so mammals eat more food per unit of body weight than most reptiles. [141]

    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.

  9. Eurytherm - Wikipedia

    en.wikipedia.org/wiki/Eurytherm

    The first is shivering, in which a warm-blooded creature produces involuntary contraction of skeletal muscle in order to produce heat. [26] In addition, shivering also signals the body to produce irisin , a hormone that has been shown to convert white fat to brown fat , which is used in non-shivering thermogenesis, the second type of human ...
