507 বছরের পুরোনো প্রাণী

This is the longest-living animal ever discovered on Earth. In 2006, scientists found a clam in the ocean near Iceland. By counting the rings on its shell, they discovered it was 507 years old, born in 1499. The clam was named Ming. Sadly, while scientists tried to study how it survived for centuries, Ming died during the research— taking the secret of extreme longevity with it forever. #factstorybengali #clam #longestlivinganimals #science #dailyfacts
