View scientific description and taxonomy

Scientific Details

At least three very different growth forms within this genus exist, but all species of Suberites have the characteristic velvety (hispid) surface. The pale yellow to cream-coloured Suberites globosus is one example.

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

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.
