Tropes pertaining to mollusks, mollusk-themed characters, and things often associated with mollusks. Seashell examples also go here, since those are often shells of a mollusk.
There are three different taxonomic groups: gastropods (snails and slugs), bivalves (clams, oysters, mussels, scallops, etc.), and cephalopods (squids and octopuses).
Sub-index of Aquatic Animal Tropes and Invertebrate Index and super-index to Cephalopod Index. See also Shell Tropes, for shelled animals in general.
