Mactra corallina

Mactra stultorum, previously sometimes known as Mactra corallina is a species of edible saltwater clam, a marine bivalve mollusc in the family Mactridae, the trough shells.


This species lives in the Black Sea, the Mediterranean coasts, and the west coast of Europe, north from Norway down to the Iberian Peninsula, and south from there to Senegal.


Seashells washed up on the beach in Valencia, Spain; nearly all are single valves of bivalve mollusks, mostly of Mactra corallina

This bivalve lives on sandy (rarely soft) bottoms at depths of between 5 and 30 m, although the shell is very often found on beaches, where it has been cast up by wave action.

Shell description

This species has a very thin and delicate shell, which has concentric growth lines and sometimes also has colored radiating bands, hence its common name, the rayed trough shell. The shell interior is white.

Human use

This species is sometimes sold in markets as a food item.
