Etymologies

Sorry, no etymologies found.

Examples

  • The term endotherm refers to animals (birds, mammals, some fishes and insects, and even some plants) that are capable of generating sufficient amounts of heat energy to maintain a high core temperature (e.g. 37-40 °C in birds and mammals) by metabolic means – usually derived from aerobic activity of locomotor muscles in animals and by unique biochemical mechanisms in plants (e.g., skunk cabbage).

    Endotherm

  • Whereas an endotherm expends a tremendous amount of energy just to maintain a constant body temperature, a cold ectotherm can pass months at a time requiring little food or oxygen.

    Amphibian

  • I'm not accusing biologists of being endotherm-centric Whiggs, but if the shoe fits ...

  • Having many functions, feathers, in addition to allowing flight can serve as an insulator (a much needed characteristic to any endotherm), also a cushion to protect the bird's fragile skeleton, its colors can be used for camouflage or even for attracting a mate.
