Reptile & Amphibian Basics

Whether you hate frogs and snakes or are fascinated by them, we hope you’ll find something interesting in this article! Reptiles and amphibians have many physical differences, but they can be grouped together for a couple of reasons. Both are cold-blooded or ‘ectothermic,’ which means their body temperatures adjust to the temperatures of their surroundings, rather than maintaining one set body temperature like humans do. So when they get too hot, they jump in cool water or hide in the shade. When they need to warm up, they bask in the sun or burrow into mud. In colder climates, reptiles and amphibains hibernate during the winter.

Amphibians and reptiles are also vertebrates: they have a backbone. The joints in between the individual vertebrae allow the backbone to be somewhat flexible.

All reptiles and amphibians, except crocodilians, have three-chambered hearts. The crocodilians need more efficient four-chambered hearts like ours, because of their size.
