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.
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 ...
An ectotherm (from Ancient 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.

The neck was short, and later species had a rather stiff trunk. These also had a more vertical tail fin, used for a powerful propulsive stroke. The vertebral column, made of simplified disc-like vertebrae, continued into the lower lobe of the tail fin. Ichthyosaurians were air-breathing, warm-blooded, and bore live young.
The giant hairy scorpion is the largest scorpion in North America and is one of the 23 species of scorpion in Nevada. [1] The fauna of the U.S. state of Nevada is mostly species adapted to desert, temperature extremes and to lack of moisture. With an average annual rainfall of only about 7 inches (180 mm), Nevada is the driest – and has the ...
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.
This list of mammals of Nevada includes mammal species living in the U.S. state of Nevada. [1] It also includes species that are now extirpated from the state. [2] [3 ...
All three species of Desmodontinae specialize in feeding on the blood of warm-blooded animals. [7] However, the common vampire bat feeds on mammalian blood more than the other two species, which primarily feed on that of birds. [8] [9] The three species resemble each other, but the common vampire bat can be distinguished by its longer thumb. [8]
