This document discusses the five main groups of vertebrates: mammals, birds, fish, reptiles, and amphibians. It provides distinguishing characteristics of each group, such as their skin/scales, how they breathe, whether they are viviparous or oviparous, examples of animals that belong to each group, and activities for classifying characteristics and choosing an animal to write about.
