This is the incredible moment when a whale shark gulped down a never-before-photographed spiraling tornado of plankton. Ocean photographer Warren Baverstock hung a single light off the back of a boat to attract the phytoplankton that whales love to eat – and then waited patiently in the dark. /VCG Photo

He was delighted when a 3.5-meter long juvenile shark rose from the depths and gobbled up the plumes of gathering plankton, and dived down to capture it silhouetted in the light. /VCG Photo

But he was astonished to then witness the microscopic plankton display shoaling behavior and spiral into a 4m tornado of "fish food." /VCG Photo
