Common Lionfish
Pterois volitans
The common lionfish (Pterois volitans) is a venomous Indo-Pacific reef fish now widely established in the western Atlantic, Caribbean, and Gulf of Mexico. It is a nocturnal ambush predator that has become an invasive species in many areas.
Identification points
- Tall, separated fan-like pectoral fins with bold brown-and-white banding
- Long venomous dorsal spines and a red-brown body with white stripes
- Head with fleshy tentacles above the eyes and under the mouth
Habitat
Coral reefs, rocky ledges, mangroves, seagrass edges, wrecks, and other structured coastal habitats, usually from shallow water to about 100 m.
Bait notes
Rarely targeted as a game fish; when spearfishing or removal-fishing, small live baits, cut bait, and jigs/soft plastics worked near structure can draw strikes. In many regions, removal by spear is more common than hook-and-line.
Behavior
A slow-moving, solitary ambush predator that shelters by day and hunts at dusk and night. It feeds on small fish and crustaceans, often using flared fins to corner prey.
Caution
Highly venomous dorsal, anal, and pelvic spines can inflict severe pain and swelling; handle only with puncture-resistant gloves and tools. Check local rules because lionfish are invasive in many places but regulations may still apply.
Fishing notes
Fish close to reef, wreck, or ledge structure and work slowly at dawn, dusk, or night. Use sturdy tackle and long-handled dehooking tools; many anglers avoid landing them by hand and instead use a landing net or puncture-resistant lip grip during removal.
