Found in warm-temperate or subtropical waters approximately 310 km of coastline with very narrow continental shelf (10-36 km wide to the 200 m isobath), however, the few sightings were all inside the 50 m isobath; on reefs with sandy or gravelly areas from close inshore to less than 50 m depth, including patches of appropriate habitat on inshore and offshore rocky banks and reefs.
