Các tia vây lưng cứng (tổng cộng) : 2; Các vây lưng mềm (tổng cộng) : 32 - 38; Tia mềm vây hậu môn: 31 - 36. Scales small with numerous tiny spinules, prominent first dorsal spine above eyes (Ref. 9002).
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); also seen feeding mid-water on zooplankton and likes to bite diver's fingers (Ref. 9002).
