Are chondrichthyes warm or cold blooded?

Chondrichthyes, which include sharks, rays, and skates, are cold-blooded animals. This means that their body temperature is regulated by their environment, and they do not have the ability to generate their own body heat. As a result, chondrichthyes are typically found in warmer waters, where they can maintain a relatively constant body temperature. In colder waters, chondrichthyes may become sluggish or even hibernate to conserve energy.
