Laternulidae
Laternulidae, common name lantern clams, is a family of saltwater clams, marine bivalve mollusks in the order Pholadomyoida.
==Description==
Members of this family have thin, brittle shells that have an elongated oval shape. The valves are white with concentric sculpturing, low umbones and a gape at both ends. The left valve is slightly larger and more convex than the right valve. The ligament is internal and there are no teeth on the hingeline. The interior of the valve is subnacreous, there are two adductor muscle scars and the pallial line has a broad pallial sinus.
The siphons are long and fused for their full length. The mantle margins are also fused except for a small gap at the anterior end.〔(Laternulidae: Lantern clams ) The living marine resources of the Western Central Pacific. Retrieved 2012-02-13.〕
