This is an unusual find on the wreck of the Rockeater, as SURG has thusfar only seen them on reefs. This species is interesting in that the male and female have different size tentacles above the eyes, where those of the male are much taller that those of the female - as can be seen from the photos, those on the female are barely distinguishable!
This blenny is named two-eyed because of the ocellate spot behind the eye, giving the appearance, from a distance, of there being two-eyes per side. It is usually a moderately skittish species, and generally requires a careful approach in order to get close-up photographs.
