Data from atomic bomb tests conducted during the Cold War have helped scientists accurately age the world’s biggest fish. Whale sharks are large, slow moving and docile creatures that mainly inhabit tropical waters. They are long-lived but scientists have struggled to work out the exact ages of these endangered creatures. But using the world’s radioactive legacy they now have a workable method that can help the species survival.
