Potato sponge
Biemna sp.*
Family Desmacellidae
updated Feb 13

Where seen? Like a potato with eyes, this buried sponge is found on some of our shores near reefs.

Features:
Spherical, oval or irregular lumpy, 10-30cm, usually buried with only chimneys sticking out of the surface. Chimneys about 1cm in diameter, 1-2cm tall. The surface is uneven and very hairy which traps sediments and sand, camouflaging the sponge. Colour pale brown.
