''Dinocardium robustum'', common name the Atlantic giant cockle, is a species of large saltwater clam, a marine bivalve mollusk in the family Cardiidae, the cockles. ==Description== ''Dinocardium robustum'' has a shell that reaches a length of 100-125 mm. This large and sturdy shell is obliquely ovate, with crenulate margins and about 32-36 rounded radial ribs present on both the inside and the outside. The valves are symmetrical with one another (equivalve). The basic color of the surface usually is creamy white, mottled with reddish-brown markings, while the interior is pinkish. This cockle burrows into the substrate by means of its strong foot, and like most bivalves feeds by filtering the water for plankton.
