This name was mistakenly used for Svenzea zeai, but it is a distinct species. Creeping cylinders and cavity-filling masses or crusts under corals and rubble in shallow water. Surface often pierced by holes. Parts of the same sponge hard, others crumbly. Bahamas material has as spicules thin oxea 92-122 x up to 2 µm arranged in the surface in a tangential unispicular reticulation, more paucispicular in the interior. Cavity filling specimens of Neopetrosia rosariensis (Zea & Rützler, 1981) may be confused with this species because they also have fields of holes in the surface. The latter are darker, almost black, hard throughout the body, often with elevated tubular oscules and thin branchelets, and have slightly larger and thicker oxeote spicules (130-175 x 3-5 µm for the Bahamas material), with points often a bit blunt or stair-stepped. |
