Arctica islandica, commonly known as the ocean quahog, is an edible marine bivalve mollusk native to the North Atlantic ocean, which is exploited commercially. This species is also known by a number of different common names, including Icelandic cyprine,[1] mahogany clam, mahogany quahog, black quahog, and black clam.[2]
The typical arctica islandica resembles the quahog, but the shell of the ocean quahog is rounder, the periostracum is usually black, and on the interior of the shell, the palial line has no indentation, or sinus. Unlike the quahog, which lives intertidally and can be collected by clam digging, this species lives subtidally, and can only be collected by dredging.
