There is always somebody bigger…even if you are the ultimate predator on top of the marine food chain.

Researchers from the ARC Centre of Excellence for Coral Reef Studies found out that it is indeed a ‘shark-eat-shark’ world out there, while diving on the Great Barrier Reef.

They discovered and snapped the first known photos of a tasselled wobbegong shark chomping into the body of another shark.

Wobbegongs usually lie in wait on the sea floor for a passing fish or a tasty invertebrate to swim by and then ambush their prey. This one got lucky with a brown-banded bamboo shark (Chiloscyllium punctatum), and was in the process of swallowing it whole and head first. The wobbegong’s appetite for large meals is helped by its dislocating jaw, large gape and rearward-pointing teeth.

While wobbegongs eating sharks has been recorded before from stomach contents, this is the first time it has been photographed in action.
