Greenland Shark

It's no fish tale: The Greenland shark is the longest-lived vertebrate on the planet, a new study says.

The largest shark in the study, at 16.5 feet (five meters) in length, was estimated to be approximately 392 years old.  Nielsen says there is some uncertainty around that estimate.  He and his colleagues determined with 95 percent certainty that the shark was between 272 and 512 years old, and it was most likely around 390.
