Morphology | Morphometrics
This species possess an anal fin separate from the ventral caudal margin by a notch. It is distinguished from its congeners by its relatively large body size; a long pre-narial length; a short pectoral-pelvic space and long pelvic-caudal space; ventral caudal margin ending slightly posterior to dorsal caudal margin; oral and preopercular lateral line canals share a short common branch, uniform caramel brown coloration, no color markings or mottling present; all fins a slightly darker brown color (Ref. 84473).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00126 - 0.00759), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Deepwater species with few large eggs.).
Fishing Vulnerability (Ref. 59153
): High vulnerability (55 of 100).
