Greenland sharks live in icy ocean depths that can approach 610 meters (2,000 feet). They swim slowly, and most of them sport parasites on their eyeballs that make them at least partially blind. Experts have estimated that the sharks can live to be more than 200 years old, judging by the growth rates of certain specimens. Not a lot is known about this mysterious fish—the first photos of a live Greenland shark were taken in 1995.
