Morphology | Morphometrics
(total): 26 - 32;
(total): 12-16. Head and pectoral fin base scaly (latter covered with cycloid scales), no scales on third dorsal fin membrane, ctenoid scales adjacent to but not overlapping base of third dorsal fin membrane. Lateral line scales short, posterior projection absent (present in specimens <88mm). Dorsal fin formula V-0N-0-1-0-1. Parhypural not fused. Nine procurrent rays in upper lobe, eight in lower lobe; in upper lobe, one procurrent ray opposite upper lobe, six opposite two epurals, two anterior to anterior epural; in lower lobe, one procurrent ray opposite lower lobe, six opposite haemal spine of second preural vertebra, one between haemal spine of second preural vertebra and haemal spine of third preural vertebra. Body with seven vertical bands of reddish-brown to black saddles (broad bands not extending onto ventral surface) (Ref. 84085).
Southwest Pacific: Tasmania, Australia and New Zealand, including the Chatham Islands.
Generally more abundant above 10m, but common in areas of broken rock on reefs in depths from 0-33m (Ref. 84085). Inhabits rock pools and sub-tidally down to 30 m. Feeds on benthic invertebrates. Spawns from May to November (Ref. 9003).
