Travelled more than 700 miles in 62 days
March 2011: A great hammerhead shark is being tracked for the first time using satellite tag technology.
A team of scientists at the University of Miami, led by Professor Neil Hammershlag, tracked one of the nomadic sharks for 62 days to uncover its northeast journey from the coast of South Florida to the middle of the Atlantic off the coast of New Jersey. The straight line point-to-point distance of 745 miles (1,200km) represents a range extension for this species. The data also revealed the shark entering the Gulf Stream current and open-ocean waters of the northwestern Atlantic Ocean.
