Greenland Sharks: Not Blind! New Study Reveals Enhanced Vision in Dim Arctic Light

• Scientists previously believed Greenland sharks were nearly blind due to parasites clouding their eyes, leading to assumptions of poor eyesight.
• A new study reveals that Greenland sharks possess a wider visual range, with retinas capable of detecting light despite the presence of parasites.
• They can perceive motion and contours in the dark Arctic light, suggesting they are active hunters rather than just scavengers.
• Lead scientist Nigel Hussey's research disproves long-held assumptions about their vision, highlighting their complex behavior and ecology.
• This discovery challenges previous beliefs, showing these long-lived Arctic predators are more capable and vigilant than imagined.

Why It Matters: Greenland sharks, once thought blind, can see in dim Arctic light, revealing them as active hunters.
