Maturity: Lm ? range ? - ? cm
Max length : 41.0 cm TL mâle / non sexé; (Ref. 1371)
Épines dorsales (Total) : 2; Épines anales: 0. Pyloric caeca 29 to 37. Scales fairly large with conical spinules arranged in widely divergent V rows or in quincunx pattern. Snout with a black margin along its leading edge only; first dorsal fin with black stripe on membrane between second spinous ray and first branched ray, otherwise generally dusky.

Estimates based on models
Preferred temperature (Ref.
