* centipedes * horseshoe crabs * insects * millipedes
The major invertebrate groups include arthropods (insects, spiders, crustaceans), mollusks (snails, clams, squids), annelids (earthworms, leeches), cnidarians (jellyfish, corals), and echinoderms (starfish, sea urchins). These groups represent a diverse array of organisms that play important roles in ecosystems.

3 of the water invertebrate groups are the annelids, arthropods and crustacean.

Segmentation is present in both groups.
