Are amphibians warm-blooded animals?

Amphibians are not warm-blooded animals. Warm-blooded animals generate their own heat in cold temperatures and cool themselves in warm temperatures, maintaining a stable overall body temperature in any weather. The body temperature of cold-blooded animals is determined by the temperature of the surrounding environment.

Warm-blooded animals must consume more food than cold-blooded ones do because it takes a great deal of energy to maintain an even body temperature. They may pant to stay cool in the heat or shiver to turn up the heat in cold weather. Cold-blooded animals will lie in the sunshine to stay warm and also shiver to generate heat when they are cold.
