Hymenogadus tenuis possess a shorter barbel (about 50% of orbit diameter) and about 10 inner gill rakers on the lower limb of the first arch when compared with H. gracilis which has barbel length of 50-70% orbit diameter and 11-15 inner gill rakers on the lower limb of the first arch (Ref. 97189).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00109 - 0.00421), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
