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).
Among the most dangerous to humans are: Great white; Tiger shark; Bull shark; Oceanic White tip; Gray sharks (territorial?) Mako; Only a few species consider people as prey. They usually attack mistaking humans for marine animals on which they feed (mammals or sea turtles). Most of the other sharks attack are provoked (feeding, spearfishing, bleeding, etc.) Sharks donât have many predators.
