Etymology: Triglops: Greek, trigla, es = red mullet + greek, ops = appearance (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 71 - 1270 m (Ref. 58496), usually 200 - 600 m (Ref. 5951). Polar; 80°N - 41°N, 70°W - 24°E
North Atlantic: found only along the east and west coasts of Greenland and at Jan Mayen and very occasionally in Ungava Bay and on the Labrador coast in Canada.

Estimates based on models
Preferred temperature (Ref. 115969
): -0.1 - 4.5, mean 1.7 °C (based on 770 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00298 - 0.01684), b=3.13 (2.93 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.2 se; based on diet studies.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
