Bivalves are unique among the molluscs for lacking a [[radula]]; they feed by siphoning and filtering large particles from water. Some bivalves are [[Fauna (animals)#Epifauna|epifaunal]]: that is, they attach themselves to surfaces in the water, by means of a [[byssus]] or organic cementation. Others are [[Fauna (animals)#Infauna|infaunal]]: they bury themselves in sand or other sediments; these forms typically have a strong digging foot. Some bivalves, such as [[scallop]]s, can swim.
