Aforia circinata, common name the ridged turrid, is a species of sea snail, a marine gastropod mollusk in the family Cochlespiridae.[1][2]
Description
The shell grows to a length of 75 mm. The slender, elongate shell is covered with a brownish epidermis. There are six evenly rounded whorls, but with a sharp carina, above which they are smooth, whilst below it they are grooved, with wider interspaces. The anal sinus is deep, about one-third of the way from the carina to the suture.[3]
Distribution
This marine species occurs in the Bering Sea and in cold waters from Alaska to Japan
