Statistics of Shark Attacks on Divers
The majority of shark attacks on divers are not fatal. This does not mean that divers should be less careful in the water, but it does support the idea
that sharks are not hunting humans for food. Fatal attacks are usually the result of significant blood loss and stress. One theory suggests that sharks
will bite their prey to make sure it is edible before eating it. Once this 'prey' item is identified as an unnatural source of food, the shark will swim
away to find more suitable food elsewhere.

Use this graph with CAUTION, remembering that scientific and media coverage of shark attack during the early part of this century was far
less inclusive than that of today. This graph indicates an overall increase in the numbers of reported shark attacks over the last century.
This apparent trend is a reflection of increased numbers of people utilizing the ocean, and enhanced media coverage over the last century.
These data do NOT support an increase in the per capita attack rate on divers worldwide. (For further information, see the
ISAF 2011 Worldwide Shark Attack Summary
) The apparent drop in number of attacks in the 1970s occurred at a time when the ISAF was not as active due to lack of funding.
