Morphology | Morphometrics
Spiral valve turns 12-15; monospondylous vertebrae 40-47; nostril diameter always greater than inter-nostril width; posterior tip of pectoral fin anterior to mid-point of paired fin interspace; the distance between axils of dorsal fins about equal to the anal fin base length; area of the first dorsal fin equal to or slightly less than the area of second; anal fin low with a moderately long base. Pale gray to pale brown in color.
Oviparous (Ref. 50449). Minimum depth from Ref. 58018.

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00157 - 0.00666), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic Level (Ref.
69278): 4.0 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref.
