Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 20; Dorsal soft rays (total): 11 - 12; Anal spines: 2; Anal soft rays: 19 - 21. This species is distinguished from its southwestern Atlantic congeners by the following set of characters: D XX,11-12 (rarely XVIII, XIX or XXI,13); A II,19-21; pectoral rays 14-15 (rarely 13); length of third pelvic ray contained 2.0-2.5 times in second pelvic-fin ray; lateral-line scales 54-63 (exceptional 65-68); total nuchal cirri 10-16; presence of pre-dorsal and pre-pectoral scales, considerably smaller than scales on body; breast usually fully scaled on males, often naked on females; two pores (rarely one pore), extend from preopercular onto opercle. Colouration: body with 5-6 (rarely 7) saddle-like bars that do not extend on dorsal fin; two large and distinct somewhat square bright white blotches usually restricted to upper lip (Ref. 123106).

Biology     Glossary (e.g. epibenthic)

Occurs in shallow reefs where it preys on small benthic invertebrates (Ref. 123106).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00399 - 0.02083), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
