The image of a dorsal fin cutting through the sea surface is iconic.

But scientists studying the stomach contents of young great white sharks off the coast of Australia

were in for a surprise when they learned that the

predators seemed to spend a lot of time patrolling the sea floor.

They have a predominantly fish-based diet, which is not unexpected for juvenile white sharks.

The most important prey species we identified was Eastern Australian salmon.

University of Sydney graduate student Richard Granger.

He and his team sorted through the

stomach contents of more than 50 juvenile white sharks that died after being entangled in shark

exclusion nets meant to protect swimmers. The overall unexpected finding was just the diversity

and importance of bottom-going species, things like stargazers, which

are buried themselves in the sand. They're quite strange for kingfish and flat-haired, but also

stingrays. People actually did not have a good idea of the particulars of great white shark diets.

As Granger points out, the sharks enjoy protections throughout the world,
