Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 108 - 114; Spine anali: 0; Raggi anali molli: 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).
