Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 13; Dorsal soft rays (total): 10 - 12; Anal spines: 2; Anal soft rays: 10 - 12; Vertebrae: 26. This species is distinguished by the following characters: D XIII,10-12 (usually 11); A II,10-12 (usually 11); pectoral-fin rays 17-19 (rarely 19); tubed lateral-line scales 16-19 (usually 17-18); total gill rakers on first arch 21-23 (usually 21-22); body depth 2.2-2.4 in SL; ventral margin of suborbital exposed (i.e. not hidden by scales); middle fin rays of dorsal and anal fins filamentous; dorsal and ventral margins of caudal fin filamentous; mainly dark brown in life except pale posteriormost parts of dorsal and anal fins and pale central portion of caudal fin; dark margins of caudal fin restricted to proximal half of fin; small dark spot at upper pectoral-fin base, but not extending into axil of fin (Ref. 117117).
This species is generally associated with rocky substrates with ample crevices and coral formations, utilized for shelter. These are captured from about 1-10 m, with considerable tidal fluctuation (10+ m), especially along the Kimberley coast. Usually in large aggregations, which feed well above the bottom on zooplankton (Ref. 117117)..
