Short description Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i ryggfenan (totalt) : 9; Mjukstrålar i analfenan: 36 - 40; Ryggkotor: 82 - 88. This moderately elongate species is distinguished by the following: body depth 13-16 times in SL; dorsal-fin origin clearly before midline of horizontal distance between origins of pelvic (ventral) and anal fins (V-A), origins of pelvic and dorsal fins (V–D) 32.5-43.1% V–A; A 36-40; vertebrae: prehaemal 30-32, prepelvic 30-33, predorsal 36-40, preanal 48-51, caudal 52-58; and total 82-88; total lateral-line scales 66-72; with a narrow band of black chromatophores along lower portion of abdominal ridge (Ref. 121637).

Mesopelagic species (Ref. 7300, 75154). Feeds on small fishes rather than shrimps (Ref. 121637).

Estimates based on models

Preferred temperature (Ref. 115969): 7.4 - 14.8, mean 9.8 (based on 296 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00219 (0.00088 - 0.00547), b=3.08 (2.86 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.1 ±0.6 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (tm=4; k >0.3; Fec=300-500 (batch fecundity)).
