Description

The hump-backed scorpionfish is a scorpionfish (Scorpaenidae) from the western Indian Ocean. The species has a stocky, brown-mottled body with a humped back and numerous skin appendages that camouflage it excellently among rocks and coral. It usually lies motionless on the bottom and, as an ambush hunter, springs on passing prey. The dorsal, pelvic and anal fin spines are venomous and give an extremely painful puncture wound; treat a sting with hot water and seek medical help if symptoms occur.
