Where seen? This black prickly sponge is sometimes seen on our Northern shores.

A small prickly bushy shape made up of lobes with many large cavities. Texture with many prickly spikes. The skeleton is made up of a large proportion of silica to spongin and it has thick, robust bundles of spicules (hard, spiky bits). Holes scattered irregularly on the surface with a membranous lip which is more obvious when the sponge is submerged. Colour is black with a purple tinge.

Another black encrusting sponge is Iotrochota baculifera and Iotrochota purpurea.

Sometimes confused with Black bath sponges (Family Spongiidae) which are usually globular dome-shaped or loaf-shaped.
