As we can see in this graphic, the diversity of frogs is a relatively low number until you look around parts of South America. This graphic is slightly outdated (2017) however South
America is still leading with the most frog species.
There are over 5,000 species of known frogs, and scientists
continue to discover new species. Frog species come in a variety of sizes and colors. They can be found in a variety
of habitats on every continent except Antarctica. Frogs are amphibians, which are cold-blooded vertebrates, meaning they
have backbones, that don’t have scales. Amphibians live both on land and in water. Other amphibians include salamander, newt, and caecilian.
