Description synthétique Clés d'identification | Morphologie | Morphométrie

Lower opercular spine downward and curved forward. Upper opercular spine short, directed outward. Ventral line of abdominal keel usually with a concave notch in front of anterior postabdominal spine (Ref. 37473).

Oceanic, mesopelagic with adults and juveniles at 200-800 m by day and 100 (sometimes shallower)-600 m by night, pre-metamorphic larvae at 100-300 m. Adults and juveniles make short diel vertical migrations. Dioecious, adult photophore complement acquired at about 16-17 mm SL (Ref. 4739). Feeds on crustaceans and small fishes (Ref. 35388).

Estimates based on models

Preferred temperature (Ref. 115969): 5.1 - 13.3, mean 8.5 (based on 336 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00804 - 0.04311), b=3.01 (2.82 - 3.20), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.41 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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

Argyropelecus olfersii (Cuvier, 1829)
