Gibbonsia metzi
A rare, camouflaged kelpfish logged in California's cold kelp forests, 10.7 to 19C, spotted year-round if you look closely.
Slender, elongated body reaching about 17 cm, built low and flattened to hug rock and kelp rather than swim in open water. Mottled brown, tan and cream stripes run along the body, breaking up its outline against kelp holdfasts and blades. A single long dorsal fin runs nearly the full length of the back, and the head has a blunt, slightly upturned profile typical of clinid fishes. Look for it perched motionless on kelp fronds or wedged into rock crevices rather than cruising the reef.
Divers find it sitting still on kelp blades or tucked against rocky substrate, relying on its striped camouflage rather than fleeing when approached. It is not a fish that swims out to greet you; slow, close looking along kelp holdfasts and understory rock is what turns up a sighting. Most reports describe brief, still encounters rather than any sustained activity.
Like other clinid kelpfishes, it has no swim bladder, which is part of why it stays glued to kelp and rock instead of hovering in midwater like many reef fish.
Sightings show no clear seasonal pattern, and the observed temperature range of 10.7 to 19C spans California's kelp diving conditions across the year, so it can turn up in any month. It is logged as rare wherever divers find it, so patience matters more than timing.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
Every logged sighting comes from California, USA, making it the only real place divers currently report this species. Within California it turns up in kelp forest dive sites, so look to the state's classic kelp diving areas rather than open sand or reef.
Mapping where Striped Kelpfish is logged…
All current logged sightings are from California, USA, within kelp forest dive sites. It has not yet been reported from any other country in diver data.
There is no detected season, and sightings span a temperature range of 10.7 to 19C, so it is considered a year-round possibility on California kelp dives rather than a seasonal target.
Look for a slender, mottled brown and cream fish about 17 cm long lying still on kelp blades or wedged in rocky crevices, with a long dorsal fin running the length of its back. Its striped, blotchy pattern breaks up its outline against kelp rather than standing out.
They reach around 17 cm in length, making them one of the smaller, easy-to-overlook fish hiding among kelp fronds.
No, they pose no danger to divers. They are small, sedentary fish that rely on camouflage and stillness rather than any defensive behaviour.
