This document provides information about vertebrates and invertebrates. It describes the main groups of each, their defining characteristics, and examples. Invertebrates are divided into 6 groups including molluscs, arthropods, and sponges. Vertebrates are divided into 5 groups - mammals, birds, fish, reptiles, and amphibians. Each group is described in detail including how they breathe, reproduce, and move. Activities at the end classify different animals and characteristics and have students write about one animal.
