Short description Morphology | Morphometrics

Dorsal soft rays (total): 15; Anal soft rays: 16. This species of the subgenus Photonectes based on the following combination of characters: dorsal- and anal-fin rays not covered with black fleshy skin; pectoral fins absent; pelvic fins inserted closer to the caudal-fin base; IV photophores 34; and IP photophores begin halfway posteriorly on the isthmus. Differs from all other species in the subgenus except Photonectes mirabilis by a barbel with a small side-branch on the terminal filament. Differs from P. mirabilis in gill filaments “normal” (vs. very reduced); jaw teeth variable length (vs. short) canines; 16 anal-fin rays (vs. 19–20); no blue luminous tissue (vs. present); and no light organs inside the lower jaw (vs. three pairs) (Ref. 87305).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 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):  3.2   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
