Great barracuda are apex visual predators that occupy mid-water station points near walls and current lines, using exceptional eyesight to ambush prey fish. Solitary adults typically exceed a metre in length and will hover motionless for extended periods before striking. Their apparent curiosity toward divers — often approaching and hovering at close range — is likely an investigation of a perceived larger predator rather than aggression. Barracuda accumulations near wall edges are a reliable indicator of productive upwellings that concentrate forage fish.
