Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 31.9 cm SL male/unsexed; (Ref. 26268)
Dorsal spines (total): 0; Dorsal soft rays (total): 108 - 114; Anal spines: 0; Anal soft rays: 92 - 97. No lateral line on ocular side. Light brownish on ocular side, with 9 to 10 indistinct dark bands; posterior parts of dorsal and fin membranes blackish; no black blotch on dorsal and anal fins and opercle (Ref. 27363).
Body shape (shape guide): elongated.
Occurs in coastal areas (Ref. 36453). Mainly feeds on polychaetes; also on other benthic preys such as gammaridean amphipods, cumaceans, and mysids. A "smell and touch" kind of predator, little is known regarding its ecology (Ref. 26268).
