Where seen? This stunning nudibranch with 'eyes' on its back is sometimes seen, on our Southern shores, on coral rubble and reefs.

Features: About 5cm long. Body long, hard with white bumps on a yellow body. Some of the white bumps have dark circles so they look like big eyes. The rhinophores are yellow too. The literally eye-popping colours and design warn predators of its unpleasant nature. When disturbed, noxious secretions appear from the bumps.
