Rusty Blenny
Parablennius sanguinolentus
The Rusty Blenny (Parablennius sanguinolentus) is a small coastal blenny of shallow rocky shores and tide pools, often showing reddish-brown mottling. It is mostly of interest to shore anglers and is not a major game species.
Identification points
- Elongate blenny body with a blunt head and large, forward-set eyes
- Rusty to reddish-brown mottled coloration, often with darker bars or blotches
- Low continuous dorsal fin and large pectoral fins used to rest on rocks
Habitat
Shallow rocky reefs, tide pools, breakwaters, and kelp/seaweed-covered coasts in the intertidal to very shallow subtidal zone; typically clings close to crevices, algae, and barnacle-encrusted structure.
Bait notes
Small pieces of shrimp, clam, mussel, squid, or marine worms work best; tiny soft plastics or baited micro-jigs can take bites when fish are visible around rocks.
Behavior
A benthic sit-and-wait fish that darts out to pick small crustaceans, worms, and other tiny prey from rocks and weed. It is territorial, wary, and usually stays very close to cover.
Caution
Handle carefully because small blennies can have sharp gill covers and may thrash around rocks; avoid keeping fish from polluted harbors or rock pools due to local contamination risk.
Fishing notes
Use ultralight tackle, tiny hooks, and minimal weight; fish slowly near rock edges, tide pools, and surge channels with a delicate presentation. Sight-fishing and short casts into cover are more effective than long casts.
