Explanation:

Amphibians are a class of vertebrates that typically have a life cycle involving an aquatic larval stage (e.g., tadpoles for frogs) and a more terrestrial adult stage. Frogs and toads (Anura), salamanders and newts (Caudata), and caecilians (Gymnophiona) are the three main groups within the amphibian class. Non - avian reptiles (like lizards, snakes) have different characteristics such as scaly skin and different reproductive methods. Monotremes are egg - laying mammals. Fishes are a different class of aquatic vertebrates with gills throughout life (in most cases) and fins.

amphibians.
