If we go by the official list of dangerous sharks (e.g. from the International Shark Attack File ISAF, an institution which analyzes and collects reports on shark attacks) the white shark (Carcharodon carcharias) ranks first, followed by the tiger shark (Galeocerdo cuvier) and the bull shark (Carcharhinus leucas).
Animal Species:Bull Shark, Carcharhinus leucas Valenciennes, 1839. The Bull Shark is one of the few sharks that are potentially dangerous to people and is probably responsible for most of the shark attacks in and around Sydney Harbour. The species is also the only widely distibuted shark that stays in fresh water for long periods of time to feed and breed.
