Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 152 - 160; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 6 - 7; Ryggkotor: 114 - 121. Body and tail silvery in color; dorsal base blackish (Ref. 6551). Branchiostegal rays: 4-6 (Ref. 36609). Pelvic fins absent in adults.

Mesopelagic species (Ref. 6808). Adults feed on lantern-fishes (Myctophidae) and possibly euphausiid crustaceans (Ref. 6739). Oviparous, with planktonic larvae (Ref. 36609). They have the ability to discharge dark brown fluid from the ink-sac when alarmed.

Estimates based on models

Preferred temperature (Ref. 123201): 4.5 - 7, mean 5.8 °C (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.5000 [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).

Trofisk nivå (Ref. 69278): 3.9 ±0.63 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).
