Reef Stonefish
Synanceia verrucosa
Reef Stonefish is a highly venomous, bottom-dwelling ambush predator of shallow tropical reefs and rubble. It is famous for blending in with rock and coral, and its dorsal spines can deliver a severe, medically urgent sting.
Identification points
- Broad, warty body with irregular skin flaps and heavy camouflage
- Large head with a wide upturned mouth and eyes set high on the head
- Twelve stout dorsal spines along the back, usually partly hidden by the skin texture
Habitat
Shallow Indo-Pacific coral reefs, lagoon flats, tide pools, seagrass edges, and rocky rubble on sandy bottoms; typically rests motionless on the seabed, often partly buried or algae-covered.
Bait notes
Not a target species and is not commonly or responsibly fished for. If encountered while fishing near reefs, avoid handling; baited rigs close to the bottom may snag one unexpectedly.
Behavior
A sedentary nocturnal ambush predator that waits for small fishes and crustaceans to pass close enough to engulf. It relies on camouflage rather than chasing prey and will remain still even when approached.
Caution
Extremely venomous dorsal spines; stings are a medical emergency and can be life-threatening. Do not handle with bare hands or feet, and seek urgent medical care immediately after a sting.
Fishing notes
No practical sport-fishing value; anglers should fish carefully around reef structure, wear sturdy footwear, and use a landing tool rather than hands if one is hooked accidentally. Release from a safe distance only.
