A great hammerhead shark was tracked over 1199 km up the western Atlantic. The work was carried out by the Rosenstiel School of Marine and Atmospheric Science at the University of Miami. The 62-day journey ran from the south of Florida northward into mid-Atlantic waters off New Jersey. The scientists think the shark was following food sources. Its movement suggested the species migrates ‘into international waters, where they are vulnerable to illegal fishing’. The great hammerhead is valued for its particularly large fins for shark fin soup. The International Union for Conservation of Nature classes it as endangered in the western Atlantic and Gulf of Mexico.
