Checked: verified by a taxonomic editorDescription Description.— Encrusting, with laterally flattened irregular digitations, now fragmented, 4.5 cm in widest expansion, digitations up to 4 cm high and 1 cm diameter. Surface optically smooth but rough to the touch, texture incompressible. Oscules not apparent, but a few openings less than 1 mm diameter are found on one of the fragments.
Colour.— Live colour not noted, in alcohol black to blackish brown, slightly lighter inside.
Skeleton.— Thoroughly confused mass of oxeas, with an indistinct tangential crust at the periphery, grading into a more dense skeletal arrangement in the interior.
Spicules.— Oxeas, sanidasters, euasters. Oxeas, perhaps separable into two categories, the smaller of which is concentrated in the surface crust, sizes overall 486-1295 × 7-36 µm, smaller: 486-593.6-760 × 7-14.8-19 µm, larger: 881-1053.3-1295 × 23-28.0-36 µm.
Sanidasters, concentrated at the surface, but also less prominently present in the choanosome, likewise separable into two categories; thinner, straight, thin-rayed sanidasters, 12-15.2-18 × 1-1.4-1.6 µm, which show fewer spines under SEM; and thicker, irregular, thick-rayed sanidasters, 12-13.3-15 × 2.5-2.66-3 µm, which show overall dense spination under SEM (sanidaster thickness measured excluding rays). Oxyasters, thin-rayed with 6-10 sparsely spined rays, moderately common in the choanosome, 21-27.9-36 µm. Strongylasters, with 8 thick rays, with spines only at the end, quite rare, so only a few could be measured: 13-19 µm.
Ecology.— Collected from among intertidal stones. The flattened condition of the digitations may be simply an effect of growing in crevices of tightly packed stones.
Etymology.— Named after Robert G. Moolenbeek, curator of Mollusca of the Zoological Museum of Amsterdam, in acknowledgement of his efforts to promote knowledge of the Oman marine fauna. [details]
