Octopuses den prolifically in the wreck's corroded cavities, using the sheltered metalwork as ideal ambush territory. They are apex invertebrate predators on the reef, controlling crab and bivalve populations across the surrounding sandy rubble. Juveniles are frequently spotted on night dives emerging to hunt under cover of darkness.
