Someone recently asked us what it means to be “cold-blooded.” For most reptile keepers, the definition is pretty simple; anything that can’t maintain its own body temperature and must rely on the external environment for heat. It’s why we all keep our snakes on heat tape and use thermostats to control temperature to ensure an optimal environment. As simple as that sounds, we thought we would perhaps take it one or two levels deeper to really get at the differences between the “warm-blooded” and “cold-blooded” creatures that inhabit our planet. Read on if interested.
