This species is hexamerous, reproduces asexually by division, and reaches a maximum size of about 2.5 mm disk diameter. This is the first six-armed species of Amphioplus and the third species of the genus known from the deep North Atlantic. The specimens from the Gulf of Cadiz closely resemble the description and images given by Stöhr (2003). This is obviously a morphologically variable species; in the range of body sizes observed in this study, key features such as the arrangement of the oral papillae and buccal scale are often not developed. It is ... : Published as part of Rodrigues, Clara F., Paterson, Gordon L.
