识别要点

Rounded, balloon-like body with extremely long slender spines.
Two dark body bars/saddles are often visible on the pale body.
Large eyes and a beaklike mouth with fused teeth; no pelvic fins.

栖息地

Shallow tropical to subtropical marine waters, especially reefs, seagrass beds, lagoons, harbors, and sandy or rubble bottoms; juveniles often use sheltered bays and estuaries.

饵料备注

Not a common sportfish; if hooked, it may take small natural baits such as shrimp, squid, or cut bait on light tackle. Small jigs and baited hooks near structure can also catch it.

行为

Nocturnal feeder that crushes snails, crabs, mollusks, and urchins with strong fused teeth; sluggish by day, can inflate when threatened, and is often solitary.

注意事项

Do not eat unless properly identified and handled by experts; pufferfish contain potent tetrodotoxin, and this species can also inflate and has long spines that can puncture skin. Handle with gloves and keep clear of the mouth and spines.

钓法备注

Use light gear and release promptly; avoid forcing it onto dry surfaces because inflation increases injury risk. Most anglers target other reef species, and this fish is usually incidental bycatch.
