The World of Animals

          Congratulations! Now that you have gone through a fun journey inside the World of Animals, we hope you have gained more knowledge and understanding about them. Remember, because of their diversity, scientists have made groups and classifications in order to make it easier for us to learn more about them. As you have read awhile ago, there are two major classifications of animals, and these are the vertebrates and the invertebrates. Vertebrates are animals with backbones, while invertebrates are animals without backbones. Under these two classifications, there are still other subgroups below them. Mammals, Fishes, Birds, Reptiles, and Amphibians are subgrooups found under the vertebrates. On the other hand, Mollusks, Protozoas, Crustaceans, Annelids, Arachnids, Echinoderms, and Insects are all found under the invertebrates.  

         Once again, congratulations for accomplishing all the tasks and taking the time and effort to know more about our fellow creatures on earth. Remember to always care for them and appreciate their unique existence!Ü
