Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 14 - 16; Anal soft rays: 14 - 19. This species differs from other species in the subgenus Photonectes in the following set of characters: blue luminous tissue in a band extending from pectoral region to pelvic fins; with short transverse streaks between OV photophores, and in patches on sides of isthmus, under lower jaw and above end of maxillary; very long gill filaments very long, extending beyond opercular opening; shorter barbel than head length, with small bulb ending in a terminal appendage with a tiny bulb at tip (Ref. 92891).

Meso- and bathypelagic (Ref. 58302).

Estimates based on models

Preferred temperature (Ref. 123201): 7.1 - 17.2, mean 10.7 °C (based on 399 cells).

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).

Trophic level (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
