updated Oct 2016

Where seen? This pale blue prickly sponge is commonly seen on our Southern shores, growing over coral rubble.

Features:
Small, covering an area of 10-15cm. The sponge can take various forms; flat spatula-like fingers, lettuce-like 'leaves', spindly branches, short thicker lobes, all emerging from an encrusting base. Younger ones may look like cabbages with upright lobes arranged in a maze-like pattern. Surface texture prickly. A few small holes at the top edges. Colours from a pale greyish blue to greenish due to the cyanobacteria that inhabit the sponge. Cyanobacteria contain a bluish pigment phycocyanin that is used to capture light for photosynthesis. They also contain chlorophyll.
