Calcareous ring with large and high radial pieces and narrow interradials. Cuvierian tubules absent. Black, with yellow podia. Spicules on tegument with tables and pseudo-buttons; tables with circular discs showing 8 holes, bearing a spire of 4 pillars, with spiny crown, hollow in the middle; pseudo-buttons plate-like with denticulate border; rods in the podia and papillae smooth, with holes at their ends; tentacles with nodulous rods.

Biology     Glossary (e.g. epibenthic)

Not known to be traditionally harvested, but in recent times, due to increasing demand, this species also appears in the processed products of some Pacific Islands; low commercial value. Collected by hand while wading on the reefs at low tide, or by divers. Found in moderately shallow water; mostly on inner reef flats of fringing and lagoon-islet reefs and shallow coastal lagoons; abundant on sandy-muddy grounds with rubble or coral patches, where it hides the posterior part of its body (Ref. 122). Inhabits the edges of reefs and under boulders. Feeds on the surface of sediments (Ref. 92930). Population densities between 0.1 and 0.2 per square meter (Ref. 122).
