Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 24 - 26; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 18 - 21. Tip of pelvic fin not reaching origin of anal fin (Ref. 13608).

Mesopelagic. Young near the surface while aged adults often descend below 1,000 m depth (Ref. 2683). Largest adults may be benthopelagic (Ref. 9851). Plankton-eaters like the other members of the family (Ref. 6744). Breed all year round (Ref. 6744). Minimum depth range taken from Ref. 27000.

Estimates based on models

Preferred temperature (Ref. 123201): 11.4 - 26.3, mean 18.3 °C (based on 1065 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.8125 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02042 (0.00806 - 0.05173), b=3.02 (2.80 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100).

Price category (Ref. 80766): Unknown.
