Wreckfish are most commonly found near deep continental slopes, oceanic islands, and seamounts, at depths ranging from 40 to 600 meters, sometimes 1000 meters, where temperatures vary from 6 to 16°C. Pelagic juveniles often associate with floating objects before descending to deeper demersal habitats as they mature. Adults mainly occupy rocky environments and wrecks, seeking cavities and complex structures for protection and feeding.
