These unusual creatures are whale sharks and other endangered species that live in tropical waters. Many people know a little about these marine giants: Whale sharks consume plankton and make a yearly migration to Australia.
But there is an essential detail about these animals that has wholly eluded researchers: Their age. Like other sharks and rays, whale sharks don’t have the bones that help scientists check the ages of other fish.
But there may be a manner to get a correct age estimate for the whale shark, after all. The solution comes in the shape of a bizarre mashup of Cold War records and marine science.
Unexpectedly, the fallout of Cold War nuclear bomb tests have helped researchers nail down the age of whale sharks for the first time.
In a new study, scientists used carbon courting to know the whale shark’s new, inner ring each year that determine the age of an individual.
