Diagnosis.
Globular sponges with hispid-bristly surface provided with numerous scattered, undifferentiated porocalices; oscules inconspicuous. Skeleton radiate, consisting of bundles of oxeas issuing from the centre and running spirally to the surface. No cortical specialisation. Megascleres protriaenes, anatriaenes, occasionally plagiotriaenes, and dominant large oxeas. Microscleres sigmaspires, which may be lacking occasionally, finely spined oxeas and/or raphides occur (from
Van Soest & Rützler 2002
).
