Are slug leech octopus clam mollusks?

Yes, slugs, leeches, octopuses, and clams are all classified as mollusks, which is a diverse group of invertebrates within the phylum Mollusca. Mollusks are characterized by their soft bodies, and many have a hard shell. However, it's important to note that leeches are not mollusks; they belong to the phylum Annelida.
