description
The first dorsal fin has 13 to 15 hard rays , the second dorsal fin 19 to 22 soft rays . This is followed by eight to ten rafts. The anal fin is like the second dorsal fin from 19 to 22 soft rays, followed by seven to ten Flösseln. The caudal fin is large and deeply split, the pelvic fins very small. Characteristic for this species is the vertical, dark banding in juvenile specimens (hence the synonym " Cybium tigris "), which in adult animals is more pronounced as a speckled pattern. Other special features are the large, upwardly curved pectoral fins and the pointed snout with a slightly elongated upper jaw. The body, the maximum length of which is 120 centimeters, is spindle-shaped or torpedo-shaped. The sideline is straight at first, then it drops down from the second dorsal fin to the middle of the body. There is no swim bladder .
