Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9 - 11; Dorsal soft rays (total): 24 - 28; Anal spines: 3; Anal soft rays: 26 - 32. Generally silvery overlaid with brassy tones; back bluish or olivaceous; lower head and lower anterior part of body tinged with red; sides with series of brown speckles which form rough narrow vertical bars; pectorals plain, other fins usually reddish (Ref. 6885).

Adults occur usually in sand beaches in surf (Ref. 2850). Viviparous, female carries the developing young (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 12.2 - 17.8, mean 15.3 (based on 49 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.00831 - 0.04372), b=2.97 (2.77 - 3.17), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm<5).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Price category (Ref. 80766): Unknown.
