Short description
Morphology | Morphometrics
Dorsal
soft rays
(total): 22-26;
Anal
soft rays: 37 - 42. Body slender and elongate; body depth 6.7-9.1% SL. Head length 11.4-14.4% SL. Lower jaw about as long as upper jaw. Long, tapering, protrusible snout. Chin barbel 11.2-12.9% SL. Barbel with slender stem, 3 branches, and a globular terminal bulb. Branches located medial to bulb and are slightly shorter to slightly longer than distance from base of branches to tip of barbel, and bear several side branches. Terminal bulb with several branched filaments near tip. Two tightly bound pectoral rays (Ref. 37039).
Mesopelagic (Ref. 58302).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic Level (Ref.
69278): 4.2 ±0.73 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100) .
