Morphology | Morphometrics
spines: 0. Head large; eyes large; snout pointed, its anterolateral margin incompletely supported by bone. Underside of the head mostly scaled. Light organ large, a lens-shaped fossa on the abdomen extending forward to midway between the anus and the pelvic fin insertions. Scales on body with small imbricate spinules arranged in as many as 24 rows. Swim bladder deeply bilobed anteriorly, pointed posteriorly.

Estimates based on models
Preferred temperature (Ref. 115969
): 8.5 - 16, mean 13.6 °C (based on 55 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00229 (0.00101 - 0.00521), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (57 of 100) .
