Skeleton: Because of the sponges’ texture and the arrangement of spicules, it is very difficult to make good skeletal preparations. Thus, information on skeletal features of observed sponges is scarce, despite a good number of preparations. Spicular arrangement irregular, basis showing tracts of smooth styles, running generally towards the apical sponge surface. These tracts either thick and dense, or very disorganized (
