Living Material

Both species are moderately abundant, and are obtained by dredging off Vineyard Haven, near East Chop, Martha's Vineyard, Mass. The most reliable feature for distinguishing between them is the shape of the arms or rays; in A. forbesi the rays are stout and cylindrical and tend to be blunt at the tip, and in A. vulgaris they are flattened and taper to a point. The sexes are separate but cannot be distinguished on the basis of external characteristics.
