Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0. Barbel length less than 20% of standard length; barbel with 5 branches apparently arising together from stem; lateralmost pair of branches, which actually arise from base of mediolateral pair, usually shortest; mediolateral pair usually longest; diameter of stem distal to branches greater than that proximal to branches; stem solidly pigmented, pigment extending onto dorsal surface of terminal bulb; terminal bulb elongate and with an unpigmented tip usually directed dorsally; swollen ventrally, its length 2.0 - 2.5 times its thickness; a single terminal filament arising ventral to bulb tip, usually about as long as distal barbel, but occasionally minute.

Mesopelagic species (Ref. 7300, 75154).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.3 ±0.8 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (11 of 100).
