Introduction: Scientists have identified and named more than 1.8 million species of animals. It is estimated that there are another 3 million to 30 million more to identify. Animals are classified into two major groups; vertebrates and invertebrates. Invertebrates are classified as animals without a backbone and make up about 97% of all animal species. Simple invertebrates include sponges, cnidarians, flatworms, and roundworms.
Task: Follow the hyperlinks below to answer the following questions
