Australia averages two fatal incidents annually (see Australian 2017 Shark Attack Summary). Swimmers and waders accounted for 22 of incidents, snorkelers/free divers 9, Scuba divers 2, body-surfers and those playing in the wave zone 3, and those participating in other shallow water activities. Significantly, there were only five unprovoked attacks that were fatal worldwide. Six attacks occurred in Western Australia, five in New South Wales, two in Queensland, and a single incident in Victoria. This is a slight decline from 2016 which saw ulrikedal pizza lund 56 unprovoked attacks, but on par with the most recent five-year annual average. 2017 USA Statistics Florida 31 South Carolina 10 Hawaii 6 California 2 Massachusetts 1 North Carolina 1 Texas 1 Virginia 1 Total 53 For decades, Florida has topped the charts for worldwide shark attacks and 2017 was no exception. The isaf does not assign too much significance to these short-term trends as annual fluctuations in shark-human interactions are to be expected. A diver is bitten after grabbing a shark, attacks on spearfishers and those feeding sharks, bites occurring while unhooking or removing a shark from a fishing net, etc. In addition, an increasing population to the area has led to more shark-human interactions. For decades, worldwide fatality rates have continued to decline reflecting advances in beach safety, medical treatment, and public awareness. Increased attention given to sharks in the media has promoted public interest in shark attacks around the world, leading to better documentation of human-shark interactions.
The United States had the most unprovoked attacks but no fatal incidents in 2017. The 10 other cases were determined to be caused by other biotic/abiotic sources. The International Shark Attack File (isaf) investigated 155 incidents of alleged shark-human interaction occurring worldwide in 2017. This represents.2 of the worldwide total.
