Greenland Sharks

Greenland Sharks

Greenland sharks have the longest known lifespan of all vertebrate. They have an average lifespan of 400 years. Unfortunately for them, they spend most of this long lifespan swimming blind despite being born with fully functioning eyes. Majority of these sharks are blind due to the fact that they have parasites hanging from their eyes. These pinkish-white parasites are called copepods, and they attach themselves to the Greenland sharks’ cornea, rendering them blind.
