Amphimedon viridis Duchassaing & Michelotti Amphimedon viridis Duchassaing & Michelotti, 1864: 81 Occurrence : Port Royal (Jamaica), submerged ruins, depth 7 m, 27 March 1964. Bimini (Bahamas), lagoon, depth m, 16 March 1964. La Parguera (Puerto Rico), mangrove, depth m, 3 May 1964. : massive, with oscule-bearing lobes. Soft, slightly mucous, dark green outside and inside in life. Soft and fragile, middle brown in formalin. Spicules: oxeas slightly curved, with sharp and well formed points, measuring 130-170 x [jim. : massive with oscules on top of digitiform processes. Soft, dull green, slightly sticky in life. Fragile, medium brown in formalin. Spicules: oxeas slightly curved, measuring 100-140 x [zm. The axial canal is visible; the extremities are generally open, truncated. : massive, with lobes and digitate processes bearing an apical oscule about 4 mm wide. When wet, it does not support its own weight. Green outside and inside, sticky to the touch in life. Olive in formalin. Spicules: oxeas slightly curved, measuring 130-160 x [j,m. They vary considerably in thickness. The points are regular, sharp. The frailness of the spicules of specimen is noteworthy, particularly when we consider that to this species have been attributed also specimens with oxeas up to 10 and even 12 (j,m thick (Little, 1963; Wells et al, 1960). I would mention that the oxeas of the two types at the Turin Museum measure respectively 120-150 x [Jim and 130-150 X [ Please note that these images are extract
