This uncommon blenny mimics the Bluestripe cleaner wrasse as a protective measure, and in times of need, feeds by pretending to clean unwary fishes by taking bits of fin, skin, mucus, and scales.  It normally feeds upon fish eggs, tube worm gills, Tridacna clam mantles, and zooplankton.  The lower law is underslung, and the dorsal fin begins just posterior to the eye.  Attains 4.5 inches.  Red Sea to Japan, and French Polynesia, excluding Hawai'i.
