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).
While sharks don't kill nearly as many people as other animals on this list, they are still one of the sea creatures you don't want to mess with. Maybe it's the multiple rows of dagger-sharp teeth or the size of their huge mouths which can swallow you whole that makes them one of the ocean's most dangerous predators.
