Diagnosis
Globular sponges with conulose or uniformly hispid surface, with few oscules, usually situated at the top. Usually with spicule strands at the base, acting as root system. Surface without porocalices. In cross section, there is no visible cortex. The skeleton is spirally radiate, with bundles of oxeas originating from a central focus and radiating in a spiral manner to the surface. At the periphery, these bundles of oxeas become mixed with triaenes, predominantly protriaenes. Microscleres sigmaspires (absent in the type species). About 50 species have been described from all parts of the world oceans, mostly from deeper localities. Since many authors did not distinguish between Tetilla and Craniella, the actual number of species may be less.
