Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. Dark brown in color (Ref. 6592). Snout long, depressed, and spatulate in form; lateral line distinct; pectoral fin long, subequal to snout; dorsal and anal fin rays abruptly become shorter near tip of tail and once again become longer, so it appears an independent caudal fin is present (Ref. 13608).

Mesopelagic (Ref. 5951). Feeds mainly on crustaceans.

Estimates based on models

Preferred temperature (Ref. 123201): 1 - 14.5, mean 7.8 °C (based on 1032 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.8750 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Nutrients (Ref. 124155): Calcium = 26.4 [9.0, 58.4] mg/100g; Iron = 0.303 [0.134, 0.816] mg/100g; Protein = 18 [16, 21] %; Omega3 = 0.176 [0.058, 0.544] g/100g; Selenium = 22.3 [7.8, 62.8] μg/100g; VitaminA = 19.8 [2.3, 158.1] μg/100g; Zinc = 0.516 [0.280, 1.006] mg/100g (wet weight);
