Two lateral lines, the lower originating below the 6th to the 7th spine of the first dorsal fin, descending sharply to ventral contour of body, dividing into a short anterior branch and a much longer posterior branch.

Estimates based on models

Preferred temperature (Ref. 123201): 13.8 - 17.6, mean 17.2 °C (based on 13 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00166 - 0.00830), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.8   ±0.5 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
