How Rainfall In Australia Helped Scientists Crack The Mystery Of Shark Aging
Scientists have discovered a new method for aging sharks by analyzing the chemical composition of their vertebrae, moving beyond traditional band counting. This technique, which uses X-ray and laser-based geochemistry, tracks strontium isotope ratios that change with seasonal rainfall and salinity shifts. The study focused on the critically endangered speartooth shark, highlighting the importance of accurate aging for conservation efforts and fisheries management. AI
