Distribution. Arctic (150–560 m), NE Atlantic (810–1095 m), E Atlantic (175–423 m), S Africa (102–200 m). SPA (135–510 m). Remarks. The MD 50 specimens are small (<1.5 mm dd) and have six arms, two distal oral papillae, fanshaped DAPs that are longer than wide with a convex distal edge and tapered proximal sides, 3 arm spines and an occasional disc spine. The smallest specimens have only 3 arms or show other signs of fissiparity. Clark (1976) tentatively referred some small six-armed SPA specimens from 40–80 m to Ophiactis savignyi Müller & Troschel, 1842 on the basis that they had two distal oral papillae, truncate lower arm spines and fanshaped DAPs with a flattened distal edge. However, although the lower arm spines on the MD 50 specimens are widened compared to the upper one, they differ from O. savignyi in being terminated in a pointed thorny apex, and the DAPS are more droplet-shaped and show no sign of a truncate distal edge. Instead, they are similar to equal-sized specimens of Ophiactis nidarosiensis from the Atlantic and Ophiactis hirta Lyman, 1879 from SE Australia/ New Zealand (e.g., MV F90159) which are also fissiparous. ...
