Introduction: scientists used to think that great white sharks were only active in the coastal area, and would not swim as long as whales But recently, scientists found that great white sharks can cross the entire Indian Ocean in just six months, and travel between the coasts of Australia and Africa The scientists owe their discovery to a great white shark named Nicole In November 2003, after Nicole was caught, scientists implanted a satellite positioning chip on her back After tracking, scientists found that Nicole traveled more than 19000 kilometers from the coast of South Africa to Australia through the Indian Ocean in half a year, and then back to South Africa It's also the first time scientists have found evidence of a link between sharks in Africa and Oceania Dr Raymond, Wildlife Conservation Association, fishery scientist: This is the first time that we have found that great white shark can cross the whole ocean Previously, we thought that it only operates in the offshore area Scientists say Nicole's behavior across the Indian Ocean is normal In addition to Nicole, the scientists also implanted the same chips in 24 other great white sharks to better understand their migration routes.
