What are some examples of ectotherm?

Ectotherms, or "cold-blooded" animals, rely on external environmental temperatures to regulate their body heat. Examples include reptiles like snakes and lizards, amphibians such as frogs and salamanders, and many fish species like trout and bass. Invertebrates like insects and certain mollusks, such as snails, also fall under the ectotherm category. These animals often bask in the sun or seek shade to maintain their body temperature.
