Suberites ficus

Sulphur sponge

   Suberites ficus is a massive sponge up to 30 cm across. It has an irregular rounded form. The surface is smooth, fibrous-like with few large oscules. The colour is variable: yellow orange, red orange, greish or brownish. It is attached to rocks, near algae and sometimes to small stones it may entirely cover. It can be seen rolling to and fro on the bottom according to water stream. It may also cover shells inhabited by hermit-crabs.
It is found from surface to 200 m deep, in the Atlantic Ocean, the Baltic Sea, the North Sea, the English Channel and the Mediterranean Sea.

Close species :

 There are other similar species of the genus Suberites such as Suberites carnosus which is more globulous, with fewer oscules (generally 2 to 3) and which can retract a lot.
