brown sponge Neopetrosia exigua* Family Petrosiidae updated Dec 11 Where seen? This smooth brown sponge forms a ridged layer over coral rubble and is sometimes seen on our Southern shores. Features: Encrusting layer covering 10-20cm or more, often with irregular low 'walls', folds, knobs and lobes. In deeper water, it may have taller lobes or turrets (to 30cm). Texture smooth and velvety (not rubbery) because the surface has a layer of tiny needle-shaped spicules. Tiny circular holes at the top of folds and scattered elsewhere. Colours ochre to golden and orangey brown. May be confused with Blue icing sponges (Lendenfeldia cf. chondrodes) which look similar but are blue, green or lilac. Also similar to Smooth green sponge which is not as smooth has has a texture of tiny bumps. |
