Red encrusting sponge

Code



Summary

This species displays a variety of different habits: It forms thin encrustations with several root-like canals from the slightly raised oscules (M. arbuscula-oscula). These canals often intertwine and connect with canals radiating from other oscules. But the species can also form erect, lobate branching, bushes, with pen-like surface projections.

To be confused with

- Orange veined encrusting sponge Rhaphidophlus venosus

Size: Up to 12 cm high and wide. The projections are 5-10 mm long, irregular in outline and spiny.
Colour: Both growth forms are brilliant red. Especially in encrusting forms, the white spots between the canals are conspicuous, forming lighter areas.
