WAILUKU, Hawaii, Nov. 24 (UPI) -- In 2012, there were eight reported shark attacks off the beaches of Hawaii. In 2013, there were another eight. Two of the 16 were fatal. In the fall of 2013, scientists began tagging and tracking tiger sharks to try ascertain a change in behavior that might explain the uptick in unprovoked attacks.
Researchers at the University of Hawaii's Institute of Marine Biology tagged 24 tiger sharks in October 2013. Several more were tagged at the beginning of 2014. Currently, satellites help marine biologists working on the shark-tracking program keep tabs on some 35 specimens.
