Notes: Excavating sponge. Fields of black papillae, often partly fused, level with the substratum, slightly elevated when relaxed. This sponge excavates the upper 1-2 cm of the substratum, filling cavities with a greenish yellow tissue. For distinction from other similar species see Zea & Weil (2003).
