Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
This species is distinguished by the following characters: with three broad dark saddle blotches before first dorsal fin, the first saddle on posterior half of interorbital region and immediately behind eye, second saddle over pectoral fin base, and third saddle at middle between pectoral
and pelvic fin bases; adults with dark and irregular spots, sometimes with white spots between the saddles (Ref. 94801).
Body shape (shape guide): elongated; Cross section: angular.
Found on rocky reefs (Ref. 12951); near shore, down to 300 m on sandy mud bottoms (Ref. 11230). Feeds mainly on bony fishes such as mackerel, sardines, filefishes, moray eels, dragonets, flatfishes and cowfishes (Ref. 12951) but also preys on elasmobranches and squid (Ref. 12951). Oviparous (Ref. 50449). Thrives and breeds in public aquariums (Ref. 12951).
Life cycle and mating behavior

Oviparous (Ref. 559), two tendril eggcases are deposited at one time (Ref. 12951). Embryos feed solely on yolk (Ref. 50449). Eggs hatch after about 1 year and size upon hatching is 16-22 cm (Ref. 12951).
