Comb greenlings ( Zaniolepis ) are a genus of fish from the order of the perch-like (Perciformes). The two species of the genus live on the ocean floor in the eastern Pacific on the North American west coast from Vancouver Island to Baja California at depths of 37 to 244 meters.
features
Comb greenlings are elongated fish that reach a length of 25 to 30 cm. The number of vertebrae is 21 to 22. The body is covered by ctenoid scales. The caudal fin is slightly forked, the dorsal fin is deeply indented between the hard-rayed and soft-rayed part. The first three rays of the dorsal fin are elongated. The first two rays of the pelvic fins are thickened and extend to the beginning of the anal fin. The fish have a single sideline .
Fin formula : Dorsal XXI – XXII / 11–12, Anale III / 16–17.
Comb greenlings feed on bristle worms , fish eggs and crustaceans such as krill and amphipods .
Systematics
The Canadian ichthyologist Joseph S. Nelson assigns the comb greenlings in his standard work on the fish systematic Fishes of the World as the subfamily Zaniolepidinae to the greenlings (Hexagrammidae). Wiley and Johnson raise this subfamily to the rank of family in their study of the systematics of the teleostei . Smith & Busby also placed the anemone guardian ( Oxylebius pictus ) in the family Zaniolepididae , so that the family is no longer monotypical.
