Exploding out of the water, a great white shark performs a backflip during a hunt for seals. The jaw-dropping moment stunned spectators watching from a catamaran near Seal Island in False Bay, South Africa. The hungry shark emerged from the water and bit down on the catamaran's dummy seal, before disappearing into the waves. Yirui Heng, of Singapore, photographed the action, which lasted for just seconds.
