Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 13 - 15; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 13 - 15. Small, stout-bodied myctophid with well developed eyes, swim bladder and associated gas gland (Ref. 9185).

Pseudoceanic, found over continental shelves and slopes (Ref. 4066). Occurs between 325-475 m during the day; between 40-250 m at night (maximum abundance in 100 m depth). Mesopelagic (Ref. 5951). In the Cariaco Trench, day distribution is at 250 m and at night at 50 m due to anoxic conditions below 400 m and free hydrogen sulphide below 375 m. Fecundity is about 1,000 eggs per female (Ref. 9504).

Estimates based on models

Preferred temperature (Ref. 115969): 11.1 - 23.6, mean 17.9 (based on 395 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00436 - 0.02294), b=3.04 (2.86 - 3.22), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.3 ±0.2 se; based on diet studies.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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