As the sea's ultimate predator the fearsome creatures patrol the ocean safe in the knowledge that they rule the waves.
But now it seems sharks shouldn't swim so easy as their bigger, hungrier cousins might view them as a tasty snack.

The experts, from the Australian Research Council's Centre of Excellence for Coral Reef Studies, knew sharks ate other sharks after discovering remains in the stomachs of carpet sharks, but it is the first time the process has been photographed in action.
