Sponges are invertebrate animals that usually have no body symmetry and never have tissues or organs. Cnidarians use stinging cells to capture food and defend themselves. Flatworms are flat and as soft as jelly. Unlike cnidarians or flatworms, roundworms have a digestive system that is like a tube, open at both ends. Earthworms and other segmented worms have bodies made up of many linked sections called segments.

What main characteristics are used to classify animals into different phyla?
Animals are classified into different phyla based on several characteristics including the body symmetry (radial or bilateral), the presence or absence of a backbone (vertebrate or invertebrate), the type of body plan (sponges, cnidarians, mollusks, arthropods, etc.), and the organization of their body systems. Additionally, characteristics like the presence of a notochord, segmentation, and the development of specialized tissues also play a role in classification.
