Short description Morphology | Morphometrics

Dorsal soft rays (total): 16-24; Anal soft rays: 15 - 21. This species is distinguished from its congeners by the following characters: 2 supraneural bones; spinous process (hypurapophysis) on the anterosuperior border of the parahypural bone (hypural complex); sagitta otolith elliptical and smooth-lobed margins, rostrum process short, posterior region of the otolith straight or flat, the aspect ratio of sagitta otoliths AR = 0.585, the roundness index Rd = 0.543; morphometric index 0.735: mean head length 35.01% SL, mean diameter of the orbit 7.73% SL, mean pre-orbital depth 0.14% SL, mean snout length 5.36% SL (Ref. 126783).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02455 (0.00939 - 0.06419), b=3.00 (2.77 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (19 of 100).
Price category (Ref. 80766):   Unknown.
