A sponge (Desmacidon fruticosum)

Distribution data supplied by the Ocean Biodiversity Information System (OBIS). To interrogate UK data visit the NBN Atlas.Map Help



Desmacidon fruticosum are orange-pink, encrusting or massive sponges that form mounds with vertical extensions. The extensions sometimes exhibit longitudinal grooves, are finely rough with stiff hairs and are usually orientated towards the water surface whatever the angle of the substratum. The excurrent openings (oscula) are small and scattered about the body of the sponge. Desmacidon fruticosum produces large quantities of mucus when out of water.

Recorded distribution in Britain and Ireland

Recorded from Northumberland, the Isles of Scilly and the Isle of Man.
