Glossoidea is a superfamily of molluscs with 22 observations.

The Pectinoidea are a superfamily of marine bivalve molluscs, including the scallops and spiny oysters.

Ostreoidea is a taxonomic superfamily of bivalve marine mollusc, sometimes simply identified as oysters, containing two families. The ostreoids are characterized in part by the presence of a well developed axial rod. Anal flaps are known to exist within the family Ostreidae but not within the more-primitive Gryphaeidae. The scar from the adductor muscle is simple, with a single, central scar. In the majority, the right valve is less convex than the left.

Astartoidea is a superfamily of bivalves in the order Carditida. In the World Register of Marine Species (WoRMS), it is considered a junior synonym of Crassatelloidea, whereas in ITIS Crassatelloidea is a separate superfamily containing Crassatellidae.

The Anomioidea are a superfamily of marine bivalve molluscs that include two families, the Anomiidae and the Placunidae, the jingle shells and saddle shells. They are mainly sessile bivalves that superficially resemble true oysters (partially in that they cement themselves to a substrate). Though they are pleurothetic, however, the Anomioidea attach via their right valve rather than the usual left. Their irregular shells are inequilateral, are round to oval, with a large byssal notch. The byssus itself is usually short and plug-like. The left valve is convex, and the hinge is considered edentu

Trigonioidea is superfamily of medium-sized saltwater clams, marine bivalve molluscs. Within the fossil record the occurrence of this superfamily is widespread, ranging from the Devonian Period to Recent.

Mytiloidea are a superfamily of small to large saltwater mussels, marine bivalve molluscs in the order Mytilida.

Poromyoidea is a superfamily of molluscs. It used to contain only the family Poromyidae, but now it also contains Cetoconchidae .

Architeuthoidea is a superfamily of squid in the order Oegopsida.

Cyrenoidea is a superfamily of freshwater bivalves in the order Venerida.

Cycloteuthoidea is a superfamily of squid in the order Oegopsida.
