Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); borealis: From its northerly distribution pattern.
Environment / Climate / Range
Marine; pelagic-oceanic; depth range 0 - 950 m (Ref. 58018). Deep-water, preferred ?
North Atlantic: north of 30°N.
Length at first maturity / Size / Weight / Age
Maturity: Lm 12.8, range 11 - 14.3 cm
Max length : 14.3 cm SL male/unsexed; (Ref. 36852); 16.5 cm SL (female)
Morphology | Morphometrics
Barbel with three branches arising together from stem; barbel stem pigmented only up to origin of branches; distal stem pigmented only in axis and small internal spots; terminal bulb roughly spheroidal with short streaks of pigment on the dorsal surface roughly outlining numerous unpigmented ovoids visible internally; ovoids not protruding above bulb surface; a single pair of laterally based terminal filaments on the dorsal tip of bulb and two or three medial filaments ventral to them; the dorsal pair longer, usually thicker, and with more side filaments than the medial filaments.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [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), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.3 ±0.8 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
