Class: Demospongiae

Color: Dark brown when living. In alcohol a yellow pigment oozes out immediately after preservation.

Sponge encrusting, uniformly spreading on the substratum. Consistency, soft and slimy when fresh. Surface conulose, conules correspond to the vertical tracts of acanthostyles. Pores are in between the conules, minute and contractile; rather abundant. Oscules not seen. Ectosome and endosome are not well differentiated. The main skeleton consists of vertical tufts of acanthorhabdostyles springing up from the substratum. Rarely, solitary acanthorhabdostyles are found erect on the substratum. Spongin is seen binding together the spicules. Smooth styles (rhabdostyles) also are present, vertically arranged. The contorted sigmas are distributed abundantly in the endosome.
