Mollusks possess several features that contribute to their complexity compared to roundworms, flatworms, and corals. They have a well-developed coelom, a muscular foot for movement, and often possess a mantle that secretes a shell. Additionally, mollusks typically have a more intricate nervous system, including a centralized brain and specialized sensory organs, as well as a complex digestive system with a radula for feeding. These characteristics enable greater adaptability and ecological diversity among mollusks.

Flatworms, Roundworms, Annelids, Mollusks, and Arthropods
Some phyla that include simple aquatic organisms are Porifera (sponges), Cnidaria (corals, jellyfish), Nematoda (roundworms), and Platyhelminthes (flatworms). These organisms often have basic body structures and are adapted to aquatic environments.

All sea sponges are invertebrates along with all types of worms, flatworms, roundworms, and segmented worms. Flatworms are like tapeworms, segmented worms are like earthworms you in in the yard. Mollusks like snails, octopus, clams, and squids are invertebrates, also arthropods like centipedes, spiders, shrimp, and insects like ladybugs are invertebrates. Echinoderms like sea stars and sea cucumbers are invertebrates.
Lophotrochozoa is a diverse group of animals characterized by the presence of a lophophore (feeding structure) and/or trochophore larvae. They also have a spiral cleavage pattern during embryonic development and can exhibit a wide range of body forms, including mollusks, annelids, and flatworms. This group includes organisms such as snails, clams, worms, and leeches.
No, mollusks are not prokaryotic. They are eukaryotic organisms, meaning they have cells with a nucleus and other membrane-bound organelles.

The sub groups of invertebrates include, sponges (Porifera), jellyfish (Cnidaria, snails and squids (Mollusca) and flatworms (Platyhelminthes). Then there are roundworms (Nematoda), leeches (Annelida), insects and arachnids (Arthropoda), and the starfish, sea urchins and sea cucumbers (Echinodermata)
