Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 19 - 20; Mjukstrålar i ryggfenan (totalt): 14-17; Taggstrålar i analfenan 2; Mjukstrålar i analfenan: 12 - 15; Ryggkotor: 34. Lateral line branching below the 4th to the 5th spine of the first dorsal fin; the upper branch reaching the middle to end of the second dorsal-fin base; the lower branch running mid laterally. Body naked except for a large scaly patch extending around the posterior portion of the lower lateral line.
