Monkey-faced Prickleback
Cebidichthys violaceus
Monkey-faced Prickleback (Cebidichthys violaceus) is a kelp- and eelgrass-associated prickleback of the northeast Pacific, especially the eastern Pacific coasts of North America. It is a long-bodied, algal-grazing nearshore fish; as a recreational target it is uncommon and mostly caught incidentally.
Identification points
- Long, eel-like body with a small blunt head and small mouth
- Mottled brown to olive-purple coloration with a pale belly
- Continuous low dorsal fin and lack of obvious separate spiny/soft dorsal fins
Habitat
Rocky intertidal and shallow subtidal zones with kelp, eelgrass, mussel beds, and surge channels along the northeast Pacific coast; often shelters in crevices and among algae.
Bait notes
Not a common gamefish. Small pieces of shrimp, mussel, squid, or clam can work if you are specifically trying to catch one; small soft plastics or baited micro-jigs fished tight to cover may also get bites.
Behavior
Mostly an herbivore that scrapes and nibbles algae and detritus from rocks and vegetation, though it may take small invertebrates opportunistically. It is secretive, clings close to structure, and is more active in sheltered nearshore habitats than in open water.
Caution
Handle carefully around rocks and tide zones; pricklebacks can twist strongly in hand, and sharp intertidal surfaces are the main hazard. No major species-specific consumption concern is well documented, but it is not a commonly kept food fish.
Fishing notes
Fish very close to rocky structure, kelp, and eelgrass in shallow water with light tackle. Use small hooks, minimal weight, and a slow presentation; most captures are incidental while targeting other nearshore species.
