A low temperature inhibits activity, and a higher temperature usually stimulates the animal.

Are amphibians cold-blooded?

Most amphibians have complex life cycles with time on land and in the water. Amphibians and reptiles are together called herpetofauna, or “herps” for short. All herps are “cold-blooded,” which means they lack an internal thermostat. Instead they must regulate body heat through their interactions with the environment.

Are arthropods asexual?
