Caribbean Bluehead Wrasse
Thalassoma bifasciatum
The Caribbean Bluehead Wrasse is a reef-associated tropical wrasse common on shallow coral and rocky reefs. Juveniles and females are yellow, while terminal males are vivid blue with a blue head; it is generally too small to be a target game fish.
Identification points
- Bright blue head and upper body in terminal males, often with a yellow body transition behind the head
- Females and juveniles are mostly yellow with a dark mid-body stripe
- Slender wrasse shape with a pointed snout and a long, continuous dorsal fin
Habitat
Shallow coral reefs, reef flats, patch reefs, seagrass edges, and rocky shorelines in warm tropical western Atlantic and Caribbean waters, usually around structure in clear, relatively shallow water.
Bait notes
Rarely targeted intentionally; if caught, it will strike very small pieces of shrimp, clam, worm, or tiny artificial jigs and flies. Small reef fish imitations and micro soft plastics can work when fished close to structure.
Behavior
An active daytime picker that feeds on small crustaceans, mollusks, worms, and other tiny reef invertebrates. It is highly social, quick to dart into crevices, and males often patrol reef territories while females and juveniles forage in loose groups.
Caution
Handle carefully because wrasses have a small mouth and can be easily injured by rough handling. Not a major food fish and not typically kept for consumption; local reef-fishing regulations may apply.
Fishing notes
Use ultralight tackle and tiny hooks near reef edges, rubble, and tide-washed shallows. Present baits slowly and accurately into cracks and overhangs; it is usually a bycatch rather than a primary sport species.
