Greenland Sharks Live Up to 400 Years; Study Reveals How They Protect Their Sight

A recent scientific study has revealed that Greenland sharks possess an extraordinary lifespan of up to 400 years and has shed light on how they maintain their vision throughout their long lives.

Contrary to previous assumptions that the species was largely blind, the research identified specific genes responsible for repairing the sharks' retinal DNA. This biological mechanism allows the sharks to protect their vision even in the deep-sea environment where they reside.

The findings not only deepen our understanding of these ancient creatures but also hold potential for future medical advancements. The study suggests that the genetic repair processes observed in Greenland sharks could inspire new avenues of research in human medicine, particularly in areas related to vision and aging.
