Molly Miller
Scartella cristata
The Molly Miller is a small blenny common on shallow rocky reefs, tide pools, seawalls, and harbor structure in warm coastal waters. It grazes algae and tiny invertebrates, and is mostly an incidental catch rather than a true gamefish.
Identification points
- Mottled brown to olive body with irregular pale spotting or marbling
- Broad, blunt head with a large continuous dorsal fin
- Short, stocky blenny shape that sits low on rocks and algae-covered surfaces
Habitat
Shallow marine hard-bottom habitats: rocky intertidal zones, tide pools, jetties, breakwaters, seawalls, coral rubble, and algae-covered rocks; often holds very tight to cover in very shallow water.
Bait notes
Not a targeted sport fish. If caught deliberately, tiny pieces of shrimp, clam, sandworm, or fish flesh may take it; small micro-jigs or tiny soft plastics worked right on the bottom can also draw strikes.
Behavior
Mostly benthic and sedentary, often perching on rocks and darting short distances when disturbed. Feeds by grazing filamentous algae and picking small crustaceans, worms, and other tiny prey from the substrate.
Caution
Has small sharp teeth and may nip if handled; use care around rocky tide-pool habitat. No major consumption issue is commonly noted, but it is generally too small to be worth keeping and local rules may protect intertidal habitats.
Fishing notes
Fish ultra-light around shallow rock and algae-covered structure with very small baits and minimal weight; work slowly and keep tackle close to the bottom. Best treated as a curiosity or bait-stealer, not a primary target.
