File shells

File shells (Lima and Limaria) are white, obliquely oval bivalves with fine radial ribs like a file and, in life, long red or orange tentacles; the flame scallop of the aquarium trade is Ctenoides. Shells are cheap and delicate. Fossil Lima occur from the Carboniferous and are common in the Jurassic.
