Toothless clam
Anodontia edentula
Family Lucinidae

This species is found buried in mudflats in the intertidal and subtidal zones. They have a somewhat elongate adductor muscle, part of which is separate from the pallial line. The hinge is essentially toothless in the adult, hence its name.

They are interesting animals, harbouring sulphur-oxidising bacteria in their gills from which they derive most of their nutrition. Many lucinids have therefore lost their siphons and their ability to filter feed, and make connection with the outside world with their piston-like feet.
