Description

The banded rockcod is a large grouper of the family Serranidae from the southwestern Pacific off the coast of Australia. The species can grow to over a metre and has a robust body; juveniles have conspicuous dark bands that fade with age. It lives on rocky reefs of the continental shelf and slope, at considerable depth. As an ambush hunter it catches fishes and crustaceans. Owing to slow growth and fishing the species is considered near threatened. It is a valued food fish and is harmless to humans.
