Bull Shark

One or several bull sharks may have been responsible for the Jersey Shore shark attacks of 1916, which was the inspiration for Peter Benchley's novel Jaws. The speculation of bull sharks possibly being responsible is based on some attacks occurring in brackish and freshwater, as well as there being certain similarities in bite marks between bull and great white sharks.
The bull shark is responsible for attacks around the Sydney Harbour inlets. Most of these attacks were previously attributed to great whites. In India, bull sharks swim up the Ganges River and have attacked people. Many of these attacks have been attributed to the Ganges shark, Glyphis gangeticus, a critically endangered river shark species that is probably the only other shark in India that can live comfortably in fresh water, although the grey nurse shark was also blamed during the sixties and seventies.
