Acanthocardia tuberculata, common name the rough cockle, is a species of saltwater clam, a cockle, a marine bivalve mollusc in the family Cardiidae. The genus Acanthocardia is present from the Upper Oligocene to the Recent.


The shell of Acanthocardia tuberculata can reach a size of about 95 mm. This shell is robust, equivalve, inflated and slightly inequilateral, with crenulated margins. The surface shows 18-20 strong radial ribs, with rows of spiny nodules. The basic coloration is usually pale brown with alternating darker concentric bands.


Acanthocardia tuberculata can be found in the Mediterranean Sea and in the Northeast Atlantic Ocean.


This species is present in the continental shelf from low tide to 200 m. Like most other bivalves, these mollusks are suspension feeders filtering phytoplankton.
