خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0. First dorsal-fin ray followed by a few small fleshy filament. Color varies, brown sometimes reddish and with a vermiculated or mottled pattern dorsally. Paler ventrally. The median fin borders dark (Ref. 1371). One barbel on the lower jaw and two on the snout.
