Petricolaria pholadiformis, common names false angelwing, or false angel wing (US), and American piddock (UK), is a species of saltwater clam, a marine bivalve mollusk in the family Veneridae, the Venus clams.
Description
Petricolaria pholadiformis closely resembles the angel wing (Cyrtopleura costata), the main distinguishing feature being that it lacks the apophyses, the spoon-shaped wings located near the beak, of the real angel wing. It grows to about 5 centimetres (2.0 in) long and is usually white. The anterior end is extended and has a rounded point while the posterior end is blunt and curved. There are ridges radiating from the beak, which are more pronounced at the posterior end, and fainter growth rings running parallel with the margin.[1]
