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).
The blue shark is considered to be one of the most dangerous sharks in the waters. It has been known to attack people, which makes it one of species of shark that people most fear. Blue sharks can grow up to 12 feet long so this is no small shark to be trying to get away from. Due to the speed and the strength of it very few of its prey have a chance of survival.
