Dorsal spines (total): 13-13; Dorsal soft rays (total): 13-15; Anal spines: 2-2; Anal soft rays: 13-15; Vertebrae: 26-26. This species is distinguished by the following characters: D XIII,13-15 (usually 14); A II,13-15 (usually 14); pectoral rays 16-18 (rarely 16); tubed lateral-line scales 16-19 (usually 17-18); total gill rakers on first arch 21-24 (usually 22-23); body depth 1.9-2.2 (mean 2.1) in SL; preorbital
usually with patch of scales, occasionally naked or with just a few isolated scales; suborbital
with single row of scales, occasionally restricted to posterior part, continuing around posterior
margin of the eye. Colouration: in life, usually charcoal to greyish with broad black scale margins on side of body, forming a network, sometimes a slight to strong yellow hue on caudal peduncle and lower sides; dorsal and anal fins are charcoal or blackish with posterior margin broadly orange (sometimes greatly reduced on anal fin); caudal fin is orange; pectoral fins with a black spot covering base, invading axil of fin; body side of pectoral-fin axil is distinctly orange; occasionally overall blackish to dark brown, including median fins except sometimes slightly orange on posteriormost portion of caudal fin; juveniles (< about 3.0 cm SL) mainly bluish grey with caudal fin, caudal peduncle, and adjacent portions of dorsal and anal fins bright yellow; Rowley Shoals, Western Australia population have very dark overall with orange portions of dorsal and caudal fins replaced with bright yellow and usually with entirely black anal fin (Ref. 131255). |
Adults occur in lagoons, steep-sided channels, and seaward reefs from 2 to over 12 m (Ref. 1602). Usually found in groups off the sides of vertical drop-offs and overhanging ledges (Ref. 1602). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699). Maximum depth reported taken from Ref. 128797. |
