Diagnosis
Caliculate, lamellate or foliose sponges (Fig. 8D–E), with a characteristically smooth, heavily armoured surface. Small, flush oscules are evenly distributed over the oscular face, each at the centre of a stellate pattern created by superficial exhalant canals. The poral face is smooth. The irregular fibre skeleton comprises primary, secondary and tertiary fibres (Fig. 8F). Primary fibres are simple and branching, not fasciculate, and are heavily cored with foreign debris. Secondary fibres are similar in size and coring to the primary fibres, and are only distinguishable by their orientation to the surface. The long, uncored, vermiform tertiary fibres arise from both primary and secondary, forming a dense mat which dominates the fibre skeleton. These fibres meander for considerable distances without branching, have no fixed orientation, do not form fascicles, and only occasionally interconnect. The consistency is firm, tough, flexible, and barely compressible.
