The Entoliidae, also referred to as the entoliids, are a taxonomic family of saltwater clams, marine bivalve mollusks in the order Pectinida. They are related to and are considered the ancestors of modern scallops. In the geological record the family contains at least seven species in five different genera, though only one is extant and it is very rare and cryptic, inhabiting the Caribbean and central west Pacific Ocean in small, disjointed populations.[1]
A significant morphological feature lacking in the entoliids but present in modern scallops is the ctenolium, a comb-like structure under the anterior auricle through which scallops are able to produce a byssal thread for attachment to a substrate. The entoliids did not/ do not secrete a byssal thread.

Entoliidae zijn een familie van weekdieren die behoren tot de orde Pectinoida van de klasse tweekleppigen (Bivalvia).
Het zijn micromollusken (ca. 4 mm) uit dieper water. De top van de kleppen is hoekig (ca. 90°) en ze hebben oortjes naast de top die ongelijk zijn van grootte. De onderzijde is cirkelrond. De bovernrand van het langere oor vertoont een rij tanden. De buitenzijde is glad of met uiterst fijne sculptuur. De binnenzijde is fijn gekorreld.
Ze leven in het Caraïbisch gebied, Hawaii en de Fiji Eilanden en kunnen opgedregd worden van diepten tot ca. 200 m.
Deze familie telt slechts weinig genera, waaronder:
