Where seen? These rounded blob-shaped animals are commonly seen on our Northern shores .

Colony about 5-10cm in diameter. Rubbery blobs forming on hard surfaces or on stones near the mid-water mark. In various shades of black, red, yellow, brown and beige.

These blob ascidians look like the ones that are sometimes used by some sponge crabs for camouflage and protection.
