Yes, molluscs fit into the group known as protostomes.

Mollusks compose of the large phylum of invertebrate animals known as the Mollusca. Mollusks have a mantle, mollusks invertebrate. Arthropods have jointed appendages, arthropods have segmented bodies
An invertebrate is an organism that lacks a backbone. The 6 groups of invertebrates are sponges, cnidarians, worms, mollusks, echinoderms and arthropods.
Arthropods have an exoskeleton. Mollusks don't.
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.
Athropods. Certainly!
a scorpion is a Arthropods
Vertebrates have spinal cords. Mollusks and arthropods do not.
