The Atlantic Semele


The Atlantic Semele, Semele proficua (Pulteney, 1799), is a close relative of the Purplish Semele, Semele purpurascens, a species presented in this column two weeks ago. The Atlantic Semele is a bivalve that may reach about 1.5 inches in size. Its shell is not as colorful as the Purplish Semele: it is usually ivory-white, internally yellow with reddish-brown or mauve speckles. The brownish ligament (the organic part that joins the shell valves and that keeps them slightly open when the animal is relaxed) is elongate, slanted.
