Morphology | Morphometrics
This species is distinguished by the following characters: no scales on midline of interorbital space throughout life; longitudinal scale series 43-49 (mean 45.9); head length 39.7-44.1% (42.4%) of SL; snout length 12.9-19.1% (15.8%) of SL; head depth 21.0-25.1% (23.0%) of SL; tip of tentacle on posterior spine of lacrimal not extending beyond level of posterior margin of maxilla (sometimes extending slightly beyond in juveniles); upper margin of orbit higher than or level with base of first dorsal spine (in lateral view) in adults, lower than in young; top of bulge on snout well below ventralmost margin of orbit (in lateral view) in adults, located between levels of ventralmost margins of pupil and orbit in young (Ref. 54479).

Estimates based on models
Preferred temperature (Ref. 115969
): 14.2 - 20.2, mean 17.7 °C (based on 27 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00454 - 0.02306), b=3.01 (2.82 - 3.20), 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
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (34 of 100) .
