Annelids, mollusks, and arthropods are classified as invertebrates, which are animals lacking a backbone. They belong to the larger group called Coelomates, characterized by having a true coelom, a fluid-filled body cavity. Annelids are segmented worms, mollusks include diverse organisms like snails and octopuses, and arthropods encompass insects, arachnids, and crustaceans, all distinguished by their body structures and developmental processes.

What are the 3 largest groups of invertibrates?
The three largest groups of invertebrates are arthropods, mollusks, and annelids. Arthropods, which include insects, arachnids, and crustaceans, are the most diverse and abundant, with millions of species. Mollusks encompass creatures like snails, clams, and octopuses, known for their soft bodies and often hard shells. Annelids, such as earthworms and leeches, are segmented worms that play crucial roles in soil health and ecosystems.
