The Greenland shark is a huge, lethargic shark that lives in arctic waters. Many live over 400 years, making them the vertebrates with the longest known lifespan in the world.

Dating back over 400 million years, shark fossils demonstrate their remarkable resilience, having outlasted the dinosaurs, survived mass extinctions, and maintained their dominance atop the aquatic food chain.

These ancient sharks live at unreachable depths but they’ve been known to come closer to the surface to feed on scraps of blubber and fish hunters throw back into the sea after cleaning their catch.

Divers can travel to Greenland or Canada to get the chance to dive with this prehistoric creature.
