Originally described from Tor, Egypt, Red Sea, it is recorded below from Turkey, and previously from Israel. This species has seldom been found since its original description. It is the type species of the genus Plocamopherus. It is black with bright yellow spots all over the body. The gills are black with a few small yellow spots, while the rhinophores are completely black. It is similar in general shape to other species of the genus and has a prominent 'keel' or 'caudal fin' in the posterior dorsal midline. It differs from other species of the genus in the nature of the latero-dorsal processes. Usually there are three pairs, and the most posterior pair, at least, are tipped with a large sphere [see Plocamopherus imperialis]. From Rüppell & Leuckart's illustration, and Ferda's photo, there appears to be only two pairs of latero-dorsal processes in P. ocellatus and these are elongately conical in shape.
