warm-blooded
Definition
Warm-blooded animals are animals that can maintain a relatively constant internal body temperature, regardless of the outside temperature. This is in contrast to cold-blooded animals, whose body temperature fluctuates with the surrounding environment.
Some examples of warm-blooded animals include mammals and birds. Mammals have fur or hair to help them stay warm, and birds have feathers.
Warm-blooded animals have a number of advantages over cold-blooded animals. They can be more active and can survive in a wider range of climates.
