Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Barbel with three slender, unpigmented branches arising together from stem; all three reaching to or well beyond barbel tip; barbel stem pigmented externally up to origin of branches; only axis of distal part of stem pigmented except for an elongate, often distally forked, patch of external pigment extending dorsally from distal section of stem almost to distal tip of terminal bulb; bulb elongate, its length well over two times in its thickness; medial and lateral terminal filaments arising from unpigmented bulb tip (Ref. 45801).
Body shape (shape guide): elongated.
Epi- and mesopelagic with most captures above 225 m fishing depths (Ref. 58302).
