The document classifies animals into six main invertebrate groups: molluscs, coelenterates, porifera, echinoderms, arthropods, and annelids. It provides examples of animals in each group and describes some of their key characteristics, such as their body structure, how they breathe and reproduce, and whether they live on land or in water. Each group is also linked to external videos providing additional information.
