View scientific description and taxonomy

Scientific Details

Members of this genus all have an encrusting form and a velvety surface, barely visible by eye, produced by a brush of protruding tips of tylostyle spicules at the sponge surface. This characteristic velvety appearance is termed hispid, and appears repeatedly throughout the Phylum Porifera.

Brief species characters:
Growth form: encrusting.
Mineral skeleton: siliceous.
Megescleres: monaxone.
Surface texture: velvety, lumpy.

Family level characters:
Suberitid sponges are characterised by their lack of a differentiated outer layer, cortex, and the absence of microscleres in all but a few species. Body form can be encrusting, massive-globular, or stalked and branching.

Order level characters:
Hadromerid sponges are often brightly coloured and are also characterised by a radial arrangement of megascleres in the cortex. The megascleres are pin-head shaped tylostyles and pointed, rod-shaped oxeas. Microscleres if present may be star-shaped, rod-shaped or spiral and are key characters when separating these sponges at the family level.
