Diagnosis
Globular sponges with conulose but optically smooth surface over most of the upper body; at the base there are bundles of spicules acting as a root. Oscules few, usually on the top. Ostia in sieve-like groups overlying subdermal cavities. In cross section there is a distinctly visible cortical layer, which is perhaps divisible in a tightly collagenous layer strengthened by radially or confusedly arranged special cortical megascleres, and a less dense outer layer in which there are many subdermal cavities. Choanosomal skeleton radiating in spiral fashion, with bundles of oxeas originating from a central focus and spiralling outwards towards the surface where they are mixed with protriaenes to protrude in groups and push up the ectosome into conical elevations. Megascleres, protriaenes, anatriaenes, choanosomal oxeas, shorter cortical oxeas. Microscleres, sigmaspires (may be lost not infrequently). About 25 species are recorded from most seas and oceans, often from somewhat deeper localities.
