Description

Aplysilla rubra is an encrusting sponge which grows in thin gelatinous layers on surfaces of 3 to 30 cm2. Its surface is covered with small lobed outgrowths, up 0.5 to 1 cm in diameter, the texture of which visually recalls that of cauliflower. Few and scattered oscules are clearly visible on the top of delicate chimneys. The colour of the red oscarella varies according to the specimens, from pale beige to red passing through various shades of orange with often shades more reddish on the top of the lobes. Specimens exposed to light are more red due to the presence of symbionts that color the surface of this sponge.

Distribution

Aplysilla rubra lives on rocks, horizontal surfaces and overhangs. It is most often found at the base of rocks. Locally very common, it is found in the Atlantic, English Channel, North Sea and Mediterranean.
