Reef Sharks are Functionally Extinct

"A massive global study of the world’s reefs has found sharks are ‘functionally extinct’ on nearly one in five of the reefs surveyed. James Cook University’s Professor Colin Simpfendorfer was one of the scientists who took part in the study, published today in Nature by the Global FinPrint organisation. He said of the 371 reefs surveyed in 58 countries, sharks were rarely seen on close to 20 percent of those reefs. 'This doesn’t mean there are never any sharks on these reefs, but what it does mean is that they are ‘functionally extinct’ – they are not playing their normal role in the ecosystem,' said Professor Simpfendorfer." - Excerpt from James Cook University
