Diagnosis
Thin lamellae to multi-caliculate sponges (Fig. 5G), with an unarmoured, micro-conulose surface. The upper part of the sponge may have a sand crust, rendering the surface smooth, but this does not form a consistent armour over the whole sponge. The fibre skeleton comprises fasciculate and lightly cored primary fibres, and uncored secondary fibres (Fig. 5H–I). Primary fibres are arranged parallel to the surface, within the thin lamellae or walls of the sponges, with fibre fascicles curving out towards both surfaces. The secondary fibres are arranged similarly. Close to the surface the fascicular primaries repeatedly subdivide into finer fibres, forming a fascicular and tangled fibre mass which supports a tangential dermal skeleton of fine fibres with a regular meshwork. These sponges are firm, tough and flexible.
