A labrisomid blenny known only from Socorro Island. The English name is the one in the literature and refers to an error in the original description, not to the fish.
To about 13 cm. Four distinct dark bars on the body with five fainter ones between and beyond them, a spotted head above and mottled below with a faint double bar running from the eye to the corner of the gill cover, and an eyespot in the dorsal fin between the second and third spines. There is a branched cirrus over each eye and a large bunch of heavily branched cirri on each side of the nape. Males are uniformly brick red over body, head and fins, and that is the single cleanest field character on the fish.
Two other Labrisomus occur here and both are real confusion risks. Against the largemouth blenny, count bars: about eight along the side with numerous small white spots on the lower head and body, against four distinct bars and no white spotting here. Against the porehead blenny, this fish has discrete bars where that one has heavy dark mottling. Both of them also carry an eyespot in the front of the dorsal fin, so the eyespot separates nothing.
Shallow rock and rubble, roughly one to ten metres, on the bottom, feeding on snails, bivalves, shrimps, crabs and worms. Recorded only from the Revillagigedo Islands. The English name is not about the fish. Hubbs published the species in 1953 as Labrisomus soccorroensis, with the “c” doubled, which is a misspelling of Socorro; the name was later corrected and the common name records the error. Listed as Vulnerable.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
