Diver with bigeye trevally. The scuba diver has frightened the school of trevally or jackfish (Caranx sexfasciatus). The trevally congregates in large schools, seeking safety in numbers. The resulting mass of fish makes it difficult for a predator to focus on a single target. The bigeye trevally can reach lengths of 120 centimetres and weigh up to 18 kilograms. It inhabits tropical and subtropical coastal waters. The diver is using a rebreather system. Photographed in Malaysia.
