Description
Gafrarium alfredense is a species of marine bivalve mollusc belonging to the family Veneridae, commonly known as Venus clams. Its shell is characterized by an oval to sub-trigonal shape, moderate inflation, and distinct concentric growth lines or ribs. The coloration typically features a white to cream base with prominent bluish-grey concentric bands, especially towards the shell margins, and sometimes faint pinkish or orange tints near the umbo. This species is a suspension feeder, burrowing in sandy or muddy substrates in intertidal to shallow subtidal zones.
