Morphology | Morphometrics
(total): 2. Two dark bands on the body, running from dorsal to ventral surface; the first broad, dark blue (brownish near margins), starting anteriorly at first dorsal fin origin on dorsal surface and isthmus on ventral surface; ending posteriorly at about the fourth ray of second dorsal fin, ventrally at about sixth ray of anal fin; second band smaller, about one-third width of first, paler brownish blue and situated close to midpoint of body; a dark, thin rim of pigmentation around orbit; ventral surface of head and lower jaw naked, except for scutes on anterolateral edges of snout; snout moderate in length, 37.9-41.3% HL (Ref. 26363).
Rarely encountered (Ref. 26363).

Estimates based on models
Preferred temperature (Ref. 115969
): 3.1 - 4.4, mean 3.9 °C (based on 24 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±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
): Moderate vulnerability (43 of 100) .
