I hesitate to post stories of shark attacks. There is such a primal fear and misunderstanding of sharks.However with more and more humans venturing into Sharks home on the regular I find it necessary.
This story is unfortunate and actually extremely rare.
This one involves a Tiger Shark ( Galeocerdo cuvier ) , photo right. This description from Wikipedia says it all.
“Although sharks rarely bite humans, the tiger shark is reported to be responsible for a large percentage of fatal shark bite incidents, and is sometimes regarded as one of the most dangerous shark species. They often visit shallow reefs, harbors, and canals, creating the potential for encounter with humans. The tiger shark also dwells in river mouths and other runoff-rich water. While the tiger shark is considered to be one of the sharks most dangerous to humans, its bite rate is low. It is second on the list of number of recorded bites on humans, with the great white shark being first. On average, three to four shark bites occur per year in Hawaii, but they are rarely fatal; one notable survivor of such an attack is surfing champion Bethany Hamilton, who lost her left arm to a tiger shark in 2003. This bite rate is very low considering thousands of people swim, surf, and dive in Hawaiian waters every day. Human interactions with tiger sharks in Hawaiian waters have been shown to increase between September and November, when tiger shark females are believed to migrate to the islands to give birth.“
