Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (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.
123201): 3.1 - 4.4, mean 3.9 °C (based on 24 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00195 - 0.01700), b=3.08 (2.83 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
