Description

The tentacled scorpionfish is a scorpionfish (Scorpaenidae) of the continental slope in the western Atlantic. The species grows to about 20 cm and has a stocky, reddish body with a large, spiny head, a long tentacle above the eye and skin flaps. As a motionless ambush predator of deeper water it lies camouflaged on the bottom and snaps at small crustaceans and small fish. The dorsal, pelvic and anal spines are venomous and can give a painful puncture wound.
