Greenland Sharks Can Survive for Centuries and Maintain Long-Lasting Vision, Despite Living in the Dark

The study suggests that these sharks have DNA repair mechanisms that help maintain their vision over centuries, which could lead to insights for preventing human vision problems like macular degeneration.
