Diagnosis

Planar skeleton, degenerate spongocytes arranged in concentric layers within bark, extending to pith regions as dispersed cells. Sponges are large fans or vases, up to 2m high and brightly coloured. The skeleton makes up the bulk of the sponge body and can be a rectangular reticulation of fascicles crosslinked by secondary fibres, or a simple reticulation of anastomosing fibres, developed in two dimensions. Fibre outgrowths at right angles to the basic two dimensional reticulum are present in several species. The choanosome is cavernous with large, sacshaped eurypylous choanocyte chambers. The mesohyl of the choanosome is usually lightly to moderately collagen reinforced, but the ectosomal region has strong collagen deposition. Sponges are yellow, green, orange, blue and purple in colour.
