Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 14 - 16; गुदा कांटा: 1; ऐनल सौफट रेज़: 7 - 9; जानवरों की रीड़ का जोड़: 28 - 31. Pectorals long and slender, reaching beyond anus but not as long as head (Ref. 6885). Dark brown or black in color; black on throat and branchiostegals (8-8) (Ref. 6885).

In the sub-arctic region, young may be found at depths between 50-300 m while older individuals occur at depths between 200-500 m (Ref. 6885). Further south, in the transition zone, young are found from 200-300 m and older individuals between 200-500 m (Ref. 6885). Oviparous, with planktonic larvae and eggs (Ref. 36655).

Estimates based on models

Preferred temperature (Ref. 123201): 1.1 - 7, mean 3.7 °C (based on 133 cells).

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

Bayesian length-weight: a=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.2 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Preliminary K or Fecundity.).

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