Where seen? These odd blue 'brains' are sometimes seen on our Southern shores, on rubble near reefs .

10-15cm in diameter. Rubbery blobs forming on hard surfaces or on stones, with meandering ridges that resembles the surface of a brain. A few small holes seen only when submerged. Usually beige with shades of pale blue or green.
