November 2011 - Researchers have successfully tracked a tiger shark tagged with a Wildlife Computers SPOT tag for twenty-six months now.
Mahmood Shivji, a professor at Nova Southeastern University in Florida, says, "We are often hearing from the sharks for a year, and in a couple cases coming up to 2 years... Just fantastic tag performance." He also shared that Wildlife Computers tags are "providing amazing insight into long-term migrations of tiger sharks."
An opportunity to view the tiger shark tracks, is documented on the group's interactive website. This site is best viewed with Google Chrome as your browser (it provides the sharpest picture), but will work with Firefox and IE9 also.
Mahmood and his group are now also deploying SPOT tags on oceanic whitetip sharks. While it's early weeks yet, results look very promising.
