Subphylum Invertebratae
The majority of the world’s animals are invertebrates. All invertebrates lack a backbone, or spine. After exploring subphylum invertebratae, you should be able to describe the characteristics of each phyla and give examples of animals that belong in each classification.
Did you save the list of invertebrate animals you created in the Warm-Up activity? Now that you have completed this topic, please review the list and further classify each of the invertebrates into the correct phyla.
