Giant Trevally

Giant trevally patrol Rock Point East in loose hunting groups, using the current-swept corner to ambush fish disoriented by the surge — they have even been documented cooperating with reef whitetip sharks to drive fish from crevices. As apex predators, they help regulate populations of surgeonfish, wrasse, and other mid-trophic reef species that would otherwise overgraze algae from coral surfaces. Their bold curiosity around divers makes for dramatic encounters when drift conditions bring them in close.
