Difference between amphibians and reptiles: Among the animals in the animal kingdom, amphibians and reptiles are the most frequently interchanged. But did you know that even in early 1800, there had already been studies showing that the two are of different classes?

A zoologist named Josephus Nicolaus Laurenti termed “Reptilia” as a separate division from “Amphibia“. Since then, it became clearer that they are different in many aspects. Let’s explore the difference between amphibians and reptiles and also similarities between them in this article.

The word “amphibia” refers to a “double life” which in turn refers to the ability of the members of Class Amphibia to live both in water and on land. Basically, the Class Amphibia is composed of three orders: Anura (includes frogs and toads), Urodela (includes salamanders), and Apoda (caecillians).

Amphibians are unable to regulate their body temperature.

After hatching from eggs, they undergo through a larval stage which can range from just 10 days up to 20 years (for some species)!

During their larval stage, amphibians breathe through their gills but later on develop their lungs as they move on to land.
