Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 19 - 22; Raggi anali molli: 17 - 19. Metamorphosed females distinguished by the following characteristics: illicium with numerous elongate translucent filaments along length; length of illicium 15.7-32.1%SL; illicium lightly pigmented along anterior margin, bearing numerous elongate translucent filaments, most of which arise from posterior margin; esca consisting of posterolateral appendage with palmate, opaque, distal tip and tapering terminal appendage with opaque distal tip; highly filamentous escal appendages in specimens larger than 44 mm, number and length of filaments reduced in smaller specimens; dorsal fin rays 19-22; anal fin rays 17-19; pectoral fin rays 15-18; upper jaw teeth 26-45; lower jaw teeth 16-32; teeth on vomer 1-3 (Ref. 86949).
Meso- and bathypelagic at 0-2000 m fishing depths (Ref. 58302).
