The question that probably consumes your thoughts right now is: Are there that many dangerous species of sharks out there?

Well, calm down. Yes there are 39 types of sharks known to have harmed humans but only three species were actually involved in unprovoked shark attacks. No, Jaws itself, better known as a Great White shark was not one of these species. Surprised? In fact, out of 1190 shark attacks between 1580 and 2005, there were only 3 provoked shark attacks, one being fatal. Each of the following species was involved in one shark attack: the Hammerhead shark, the Blue shark and the Shortfin Mako shark. The fatal attack was done by the Hammerhead shark.

So according to the ISAF (International shark Attack File) between 1580 and 2005, there were 1187 unprovoked shark attacks done by 36 types of sharks. In fact, 17 of the 36 species involved in unprovoked shark attacks were responsible for 5 shark attacks or less. These types of sharks are: the Galapagos shark, the Tope shark, the Silvertip shark, the Spiny Dogfish shark, the Tresher shark, The Bignose shark, the Smooth Dogfish shark, the Basking shark, the Horn shark, the Sixgill shark, the Whale shark, the Greenland shark, the Whitetip Reef shark, the Porbeagle shark, the Leopard shark, the Mako shark and the Great Hammerhead shark.

Of the 13 types of sharks that are left, 3 species are responsible for 14 to 19 unprovoked shark attacks. These are the following types of sharks: the Spinner shark, the Blacktip Reef shark and the Bronze Whaler shark.

Of the 10 types of sharks that have been involved in 23 to 27 unprovoked shark attacks on humans, you have the 3 following shark species: the Lemon shark, the Caribbean Reef shark and the Wobbegong shark.
