Summary Introduction

Introduction:

The class amphibian is known to be evolved from lobed bony fishes. In the early Devonian period, these bony fishes evolved to form amphibians. This class of chordates is capable of living in a variety of habitats. The organisms of this class start their life, in larval form, from an aquatic environment, and an adult amphibian organism is terrestrial in nature.
