VIDEO: Chasing great whites

Posted:

(WTLV) The ocean's apex predator has been spotted off Florida's coast several times in the last year and University of North Florida Shark researchers are hoping to learn why.

"We know that white sharks have been using this area for thousands of years," said University of North Florida Shark Biology Program Assistant Professor of Biology Dr. Jim Gelsleichter.

Now, UNF's Shark researchers are recording visits from tagged great whites.

About 20 white sharks were tagged with acoustic tags in Massachusetts by the state's Division of Marine Fisheries and are detected when swimming past an acoustic receiver, but the nonprofit organization OCEARCH tagged five additional sharks with satellite tags, giving up-to-the minute tracking information every time the shark comes to the surface.
