The Channeled rockfish (Setarches guentheri) is a saltwater fish of the family Setarchidae that grows up to 31 cm.
Widespread in deep water of warm and temperate seas worldwide, on soft bottoms of the continental slope area.
Description
The channeled rockfish is a reddish scorpionfish of the family Setarchidae reaching about 31 cm and, unlike most relatives, living in deep water. The flabby, thin-skinned body has conspicuously large eyes, an adaptation to the gloom, and a shallow groove along the base of the dorsal fin. The dorsal, pelvic and anal fins bear venomous spines. The species is widely distributed on soft bottoms of the continental slope of warm and temperate seas worldwide. Close to the bottom it preys on small fish and crustaceans. Because of its deep lifestyle it is only rarely seen; a caught animal must be handled with care because of the venomous spines.
