Icy Water Temperatures
Greenland sharks are the only species that live in the subarctic. The northernmost shark species they survive in waters so cold it would turn other sharks into ice cubes. Their flesh has high levels of urea and TMAO that work as an antifreeze.
Greenland sharks are blind because there are parasites that feeds on their eyes which leads the sharks to go blind.
Greenland sharks eat fish mostly. However, they have been known to eat large sea mammals and animals that are too close to the edge of the ice. Greenland sharks will eat anything they can fit in their mouths including reindeer, horses, and very rarely polar bears.
Their flesh's antifreeze technology helps them survive the arctic water but the high levels of TMAO make it toxic for humans. If a human consumes the sharks skin tissues they will die due to the high amount of TMAO.
Sloths of the Sea
Greenland sharks are very slow swimmers and are also known as the "sleeper shark." They only swim at about 1 mph which allows them to sneak up on their prey very quietly.
Greenland sharks live to 200 years. They grow very slowly only about 1 cm a year for 100 years.
Greenland sharks are hunted for their meat and liver oil. Jeremy Wade did a TV special debunking the belief that the Loch Ness Monster existed. The so called "Loch Ness Monster" was simply only a greenland shark.
