All insects present an exoskeleton, so all insects are arthropods.

Each type has a specific name.
Actually, a sea anemone is none of these. Sponges are sessile creatures, arthropods have exoskeletons, and fish swim. Sea anemones are a type of cnidarian. They often reproduce by releasing polyps. They are related to corals and jellyfish.
