10 Most Dangerous Shark species 
(Shark Accidents in 2011)
Sharks are not harmless. They are wild animals like lions or crocodiles. Accidents happen, but not that often. To put shark accidents at the center of attention in discussions, branding them as "trademarks" of sharks, is criminal and reflects a distorted picture of these animals.
The frequency of shark accidents has been increasing since the beginning of this century. From 2000 to 2004 there were 57 to 78 shark accidents per year worldwide recorded by the ISAF (International Shark Attack File) which occurred during nonprofessional water activities. Out of these accidents 4 to 11 were fatal. In 2004 there were 7 fatal accidents.
Yet shark accidents must be seen in direct relationship to the number of water activities pursued by humans. Each year billions of people bathe, swim, dive or surf in the ocean.
Compared with about 15 billion bathing, swimming and surfing events each year, 50 to 100 shark accidents are extremely few. Still, the number of unrecorded cases is higher because third world countries rarely inform about such shark accidents for image reasons. On the other hand, the ISAF even registers the most harmless of scratches as shark attacks, even though these are in reality only "shark contacts".
