Danish scientists reckoned this Greenland shark was 512 years old–born when Henry VIII was just fourteen. Wow.
Greenland sharks can live under the polar ice cap and occasionally come down as far south as the St. Lawrence River. They can grow up to 20 feet long, but they’re most closely related to dogfish–the little sharks you catch when you’re trying to catch something else.
Five hundred years old would make this shark the oldest living vertebrate on the planet.
One wonders how long some of the dinosaurs lived.
