Sharks have a reputation for having voracious appetites, but a new study shows that most coral reef sharks eat prey that are smaller than a cheeseburger.
Researchers from James Cook University's ARC Centre of Excellence for Coral Reef Studies examined stomach contents of reef sharks and conducted chemical analyses of shark body tissue to find out what they had been eating.
Lead author, Dr Ashley Frisch said that after pumping a shark's stomach to identify the contents of its last meal, the most common thing to find was in fact, nothing.
