Oceanic Triggerfish
Canthidermis maculata
Sighting evidence at Keiten Maru, Rabaul
Oceanic triggerfish appear over the Keiten Maru in the dry season months when current patterns bring cleaner offshore water into the harbour, feeding on jellyfish and surface-drifting zooplankton. They are typically spotted as solitary individuals circling the highest point of the mast in mid-water, giving them an otherworldly presence above the busy wreck below. Their seasonal visits offer a reminder that even sheltered harbour wrecks connect to the wider oceanic food web.
