Lunchtime: Australian researchers snapped this extraordinary sight in August while they were carrying out a census of fish off Great Keppel Island off the Great Barrier Reef

You would think being shark you wouldn't have to watch your back.
As the sea's ultimate predator the fearsome creatures patrol the ocean safe in the knowledge that they rule the waves.

This is believed to be the first time scientists have ever photographed a shark eating another shark.
Australian researchers snapped the extraordinary sight in August last year while they were carrying out a census of fish off Great Keppel Island off the Great Barrier Reef.

Tasty: The photo shows a type of carpet shark called a tasselled wobbegong, munching on a brown-banded bamboo shark head first, thanks to its remarkable ability to dislocate its jaw

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.
