Lesson Excerpt:

All animals are classified into groups according to things they have in common with other animals in that group. For example, animals with hair are not in the same groups as animals with feathers. The first major difference that separates groups of animals is whether or not they have backbones. Animals with backbones are called vertebrates. Animals without backbones are called invertebrates. Each of these groups is divided into even smaller groups.

Examples of groups of invertebrates are sponges, flatworms, roundworms, segmented worms, mollusks and arthropods. Sponges have hollow tubes with holes called pores throughout their bodies. Flatworms, as the name suggests are flat worms! They have heads and tails but do not have true organs like stomachs, lungs, etc. Roundworms have round bodies, a digestive system and a nervous system. Segmented worms are more complex than flatworms and roundworms.
