Espinas dorsales (total) : 0; Espinas anales: 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. Marbled coloration on the back (Ref. 35388).

Lives generally at shallow depths near the shores on rocky bottom with aquatic vegetation to 60 m depth. Feeds on fish, crustaceans, worms and algae. Sold fresh in markets, also made into fish meal (Ref. 1371). Caught as a by-catch by various fishing gears (Ref. 35388).
