What is a Frog?


There are around 3,900 species of tailless amphibians, or Anura, also called Salientia, including the frog and toad.

Amphibians

Frogs are members of the zoological class called Amphibia.
Amphibians are cold-blooded (or poikilothermic) vertebrate animals. They differ from reptiles in that they lack scales and generally return to water to breed.
They are one of three types of Amphibians. Anura, also called Salientia, (frogs and toads), caudate (salamanders and newts) and caecilians (worm-like amphibians).
