Summary:

- A new study has found that bowhead whales, an endangered species, can live up to 150 years, which is twice as long as previously thought.
- Researchers analyzed the amino acids in the eye lenses of bowhead whales to determine their ages, which is a more accurate method than counting growth layers in their earwax.
- The findings suggest that bowhead whales are the longest-lived mammals on Earth, surpassing the previous record holder, the Greenland shark, which can live up to 400 years.
