endothermic
Ectotherms their body temperature changes with the environment
Endotherms are warmblooded, ectotherms are coldblooded, so amphibians are ectotherms.
Salamanders are endotherms.
No, a dolphin is a mammal and all mammals are endotherms.
Ectotherms have lower metabolic rates than endotherms because they rely on external sources of heat for regulating their body temperature, while endotherms generate heat internally. Endotherms have higher metabolic rates to maintain their body temperature within a narrow range, compared to ectotherms whose metabolic rates can vary more with environmental temperature.

The opposite of ectotherms are endotherms, which are animals that regulate their body temperature internally through metabolic processes rather than relying on external sources of heat like ectotherms. Examples of endotherms include mammals and birds.
All mammals are endothermic (warm blooded). Ectotherms are cold blooded animals like snakes and lizards.
Ectotherms cannot live in a great variety of environments because they cannot produce their own body heat and rely on their environment (like the sun) to maintain their body temperatures. Therefore, ectotherms have to live in relatively warm climates. Endotherms, on the other hand, produce their own body heat and do not rely on the environment as much to maintain their body heat, so endotherms can live in a greater variety of environments.
