Acanthocardia spinosa, the sand cockle, is a species of saltwater clams, marine bivalve molluscs in the family Cardiidae.[1][2]

Description

The shell of Acanthocardia spinosa can reach a size of 60–95 mm. This shell is robust, round with a heart-shaped profile, equivalve and inflated, with crenulated margins. The surface shows thick narrowly spaced radial ribs, with rows of pronounced thorny hooks. The basic external coloration is usually pale brown; the interior is white.

Distribution and habitat

Acanthocardia spinosa can be found in the Mediterranean Sea and the eastern Atlantic.[2] This species is present in sand and mud, from low waters to 120 m. Like almost all bivalves, these mollusks are phytoplankton feeders.
