Anadara transversa (Say, 1822)
It is a marine bivalve with a thick, strongly ribbed shell. The hinge line bears numerous teeth, arranged in a line on both valves. Both valves have prominent beaks which are set close to the anterior end and curved inward. The shell is heart-shaped in a side view. The shell is somewhat oblong, with straight shoulders below the beak. Both shells have about 12 radiating ribs. The shell is white, but it is covered with a brown periostracum. This bivalve does not have a siphon. This shell typically reaches 25 mm. Ark shells occasionally attach to rocks and shells with byssus threads.
