Spirastrella pachyspira   Levi,  1958 (Sponge)
Organism information awaits expert curation
Class: Demospongiae

Color: When alive it is usually violet, though pink is noted in some parts. Interior pale yellow.

Body encrusting irregularly. Face irregularly conulose or ridged. Tylostyles project out of the surface. Fleshy but slightly compressible. Oscules and pores are not visible in the living condition. A definite dermal skeleton is absent. Outer part slightly pigmented. Endosome dense and charged with microscleres. The modified spirasters form a sort of plate by the interlocking of their spines and this plate is distinctly seen in boiled,out preparations. From the upper part of the plates, deeply buried in the tissue, emerge the tylostyles in groups. These spicules are plumosely arranged. In some places the tylostyles emerging from the adjacent brushes converge and usually such an arrangement is noted in surface ridges.
