Summary:

- A new study has found that North Atlantic right whales can live for over 130 years, making them one of the longest-lived mammals on Earth.
- The study analyzed the growth patterns and age of right whales using a novel technique that examines the chemical composition of the whales' earbones.
- This discovery has important implications for conservation efforts, as it means these endangered whales have a much longer lifespan than previously thought, requiring more long-term protection and management strategies.
