Giant trevally use the Tokashiki wall as an ambush corridor, launching high-speed attacks from depth into the fusilier schools that hover above the reef crest in the current. Individuals exceeding one metre are common here, a size class that has disappeared from many fished reefs throughout the region. Their presence in large numbers is a reliable indicator of the prey fish biomass sustained by the Kuroshio Current nutrients washing across the wall face.
