Class: Demospongiae
Order:Halichondrida
Family:Heteroxyidae

Description
Surface hispid due to the presence of spicular brushes emerging from the surface. Skeleton consists of irregular ascending tracts along the central part forming a compact axial part. Fibers diverging to the surface start from this axial part. Oxeas dominate in the axial part whereas styles in the extra-axial fibers. In the extra-axial fibers styles may be seen in the central part surrounded by smaller oxeas. In the dermal part the styles project out forming surface brushes. Acanthoxeas are often associated with the dermal part though their presence in deeper areas cannot be ruled out.
Spicules: Styles long, slender size up to 2.7 x 0.018 mm. Slender oxeas evenly curved or toxiform; size up to 1.14 x 0.012 mm. Stout oxeas, evenly curved and sharply pointed; size 0.66 x 0.94 x 0.008-0.036 mm. Acanthoxeas centrangulated with a central belt of longer spines; spined all over, but younger forms sometimes smooth; size 0.07-0.148 x 0.002-0.006 mm.
