Biology     Glossary (e.g. epibenthic)

Found on the continental shelf and continental slope (Ref. 75154). Inhabits rocky reefs (Ref. 89707). Juveniles are found at depths between 15 and 128 m. Occurrence at lesser depths in the south off New South Wales is probably related to the cooler sea temperature.
