Short description Morphology | Morphometrics

Dorsal spines (total): 19; Dorsal soft rays (total): 14-15; Anal spines: 2; Anal soft rays: 12 - 13; Vertebrae: 34. Body moderately elongate and compressed. 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. The pelvic fin represented by 1 spine and 2 tiny soft rays in smaller specimens but entirely absent in specimens over 10 cm SL. Body color is brownish, fins hyaline; first dorsal fin with a black blotch distally on two anterior membranes.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00417 (0.00183 - 0.00952), b=3.08 (2.87 - 3.29), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (25 of 100) .
Price category (Ref. 80766):   Unknown.
