This structure exists in bivalves, cephalopods, and in many aquatic gastropods, i.e. in some freshwater snails and sea snails and also in some sea slugs. Some aquatic gastropods possess one ctenidium, others have a pair of ctenidia (the plural form of the word). A ctenidium is shaped like a comb or a feather, with a central part from which many filaments or plate-like structures protrude, lined up in a row. It hangs into the mantle cavity and increases the area available for gas exchange.〔(Respiratory system ) The apple snail. Retrieved 2012-04-20.〕 The word is Latinized but is derived from the Greek ''ktenidion'' which means "little comb", being a diminutive of the word ''kteis'' meaning comb.
