A dark cloud developed ahead of me. Curious, I swam nearer to investigate. The cloud billowed getting bigger and darker. Inside flashes of silver struck like a highveld thunderstorm. The cloud undulated with tumultuous movement. It was massive. As it twisted towards me I made out the characteristic shape of barracudas—the long sleek body, dark chevron markings and the mean looking straight jaw line. Thousands and thousands of barracuda were swimming together in tight synchronized formation.
