This black prickly sponge is sometimes seen on our Northern shores.
Features: 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. |
