This PowerPoint discusses the 5 main classes in the animal kingdom: mammals, fish, reptiles, amphibians, and birds. The first slide is linked to each class and will go straight to it when you click a specific class. Each slide also has a "home" button for you to easily return to the first slide. This PowerPoint is editable so you can add and change as you wish! There is also a slide on the difference between vertebrates and invertebrates with various examples.
