Animals: Vertebrates and Invertebrates

These sites explain how vertebrates and invertebrates are classified in the animal kingdom. There is information about the five groups of vertebrates (fish, amphibians, reptiles, birds, and mammals) and the seven phylum of invertebrates (sponges, coelenterates, echinoderms, worms, mollusks, and arthropods). Includes games that have students guess a type of animal based upon clues about its characteristics. For more information about specific animal species, browse our alphabetical listing of eThemes animal topics.
