Is there such a thing as a ‘problem shark’? Plan to catch repeat biters divides scientists

First was the French tourist, killed while swimming off Saint-Martin in December 2020. The manager of a nearby water sports club raced out in a dinghy to help, only to find her lifeless body floating face down, a gaping wound where part of her right thigh should have been. Then, a month later, another victim. Several Caribbean islands away, a woman snorkelling off St Kitts and Nevis was badly bitten on her left leg by a shark. Fortunately, she survived.

Soon after the fatal incident in December, Eric Clua, a marine biologist at the École Pratique des Hautes Études in Paris, got a phone call. Island nations often ask for his help after a shark bite, he says, “because I am actually presenting a new vision … I say, ‘You don’t have a problem with sharks, you have a problem with one shark.’”
