Morphology | Morphometrics
Compared to other species of Bathycongrus, its eye is larger, 16-18% HL (versus 13-18%); it has a single row of midlateral melanophores (holotype), representing remains of the pigment of the leptocephalus (versus 3 rows) (Ref. 36324).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 27.5, mean 27.2 °C (based on 5 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00062 (0.00028 - 0.00135), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
