Blue-headed Wrasse
Thalassoma amblycephalum
A small Indo-Pacific wrasse with a blue to blue-green head and a more yellowish body, usually seen over coral-rich reef slopes and lagoon habitats. It feeds on small benthic invertebrates and is a common, active reef species rather than a targeted game fish.
Blue-spotted Cornetfish
Fistularia commersonii
Blue-spotted Cornetfish is a long, pipe-like reef fish with a blue-spotted brown body and an extremely extended tail filament. It is a marine predator of shallow tropical reefs and lagoons; it is not a common target for anglers.
Blue-spotted Sunfish
Enneacanthus gloriosus
Blue-spotted Sunfish is a small, secretive centrarchid of quiet, heavily vegetated waters in the southeastern United States. It forages on tiny aquatic invertebrates and usually stays close to cover; reports outside its native range should be treated cautiously because occurrence records can include misidentifications or introductions.
Bluefin Leatherjacket
Thamnaconus degeni
Bluefin Leatherjacket is a small to medium filefish known from scattered global occurrence records, but detailed life-history information is limited. It is likely a reef-associated species with a compressed body, suited to sheltering among structure and picking at benthic prey.
Bluefin Trevally
Caranx melampygus
Bluefin Trevally (Caranx melampygus) is a fast, hard-fighting jacks species found on tropical Indo-Pacific reefs, lagoons, and drop-offs. Adults are prized by anglers for explosive strikes and aerial runs; they can be wary in clear water and are best targeted on tides.
Bluefish
Pomatomus saltatrix
Bluefish are fast, aggressive coastal predators known for feeding in schools and slashing through baitfish. They range widely in temperate and subtropical waters and are a popular sport fish where abundant.

Bluehead Chub
Nocomis leptocephalus
Bluehead Chub is a small, stream-dwelling cyprinid native to the eastern United States, especially clear upland rivers and creeks. Males build pebble nests in spring, often creating nest mounds that are easy to spot in shallow riffles and runs.
Bluespine Unicornfish
Naso unicornis
Bluespine unicornfish is a large coral-reef surgeonfish recognized by the forward horn-like projection on the forehead of adults and the sharp scalpel near the tail. It grazes mainly on algae and commonly moves in loose schools along reef slopes, lagoons, and outer reef drop-offs.
Bluespot Butterflyfish
Chaetodon plebeius
Bluespot Butterflyfish (Chaetodon plebeius) is a reef-associated butterflyfish from the Indo-Pacific, named for the bright blue spots along its upper body. It is generally an obligate coral feeder and is rarely targeted by anglers.
