Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 109 - 139; Spine anali: 0; Raggi anali molli: 80 - 106. In addition to meristic counts, B. multibarbata differs from B. townsendi by possessing a larger eye (width>interorbital space) and having slightly different coloration (dark brown with a submarginal black band and narrow white border on the dorsal and anal fins versus greenish to orange brown with orange-bordered dorsal and anal fins).
Body shape (shape guide): elongated; Cross section: compressed.
Benthopelagic on shelf and upper slope (Ref. 34024). Larvae found in the epipelagic far offshore (Ref. 34024). Found in shallow lagoon and seaward reefs and occurs at depths of at least 220 m. Adults (30-90 cm) move to depths of 100-650 m (Ref. 58472). A nocturnal species, rarely seen for it lives in caves and crevices during the day and periodically emerges from cover at night to feed on crustaceans, mainly crabs, and fishes. Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Utilized fresh and eaten steamed, pan-fried and baked (Ref. 9987). Also Ref. 58302.
