Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 0; Mjukstrålar i ryggfenan (totalt): 8; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 7. Upper side grey or brown with poorly defined black spots and saddles. Belly yellow to white. Tiny jet-black pepper spots (about 1 mm in diameter) scattered over most of pigmented surface, particularly evident on cheeks. Lower sides with a row of black, elongate, bar-like markings. No lappets on head or body (Ref 53033).
