Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 31.0 cm TL male/unsexed; (Ref. 9563); common length : 25.0 cm TL male/unsexed; (Ref. 9258)
Indo-West Pacific: New Zealand and Australia (southern Western Australia to New South Wales and Tasmania).
Inhabits rocky weedy areas from the shore to at least 60 m. Generally solitary but may aggregate in groups of 10-15 individuals in midwater. Feeds mainly on sessile and encrusting organisms, with sponges and ascidians predominating (Ref. 26966). Feeds on bottom invertebrates, also seen feeding mid-water on zooplankton, likes to bite diver's fingers (Ref. 9002).
