3. Greenland shark
If you don’t know about the Greenland shark, it’s the longest-lived vertebrate, according to LiveScience. The animals can survive for centuries (yes, centuries!) and can grow up to 24 feet long (7.3 meters), making them even longer than great whites. They occupy frigid waters off Greenland (hence its name), but also elsewhere in the Arctic and Atlantic oceans and have been found up to 8,700 feet (2,647 m) beneath the ocean surface. As you can see in the above photo, a kind of ocean parasite takes up residence in the shark’s eyes, leaving them partially blind. So yeah, our third-place shark is the very, very old, mostly sightless Greenland shark.
