Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; demersal; depth range 0 - 10 m (Ref. 9002). Subtropical
Southwest Pacific: southeastern Australia only.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm SL male/unsexed; (Ref. 33616)
Dorsal spines (total): 17; Dorsal soft rays (total): 18 - 20; Anal spines: 3; Anal soft rays: 6 - 7; Vertebrae: 35. Adults have a short-based anal fin, pectoral fins with thickened lower rays, and are grey to blue-black with lighter mottling on the sides and light spots on the fins (Ref. 33616). It is distinguished from its congeners in having larger body scales (lateral-line scales 72± 82 vs. 83± 120) and absence of vomerine teeth (Ref. 86913).
Body shape (shape guide): elongated.
Found on shallow exposed rocky shores, aggregating in high-energy zone, just below foaming surface to depths of about 10 m (Ref. 9002); in kelp and weed areas (Ref. 86913). Feed on either loose or attached weeds and algae (Ref. 9002); mainly consisting of Corallina pilulifera,
together with smaller quantities of Ulva actuca, Jania and filamentous species such
as Sphacelaria sp. (Ref. 86913).
