Greenland Shark That Eats Polar Bears Filmed by Diver [VIDEO]

If you thought great white sharks were terrifying, think again.

One diver filmed a shark rarely seen in the deep blue known as the Greenland shark, capturing a video of one of the largest species of shark which feeds on polar bears and can live up to 200 years.

A marine wildlife photographer, 59-year-old Doug Perrine of Hawaii, ventured into the St. Lawrence River in North America where Greenland sharks sometimes visit. Perrine was brave enough to come within a few feet away in order to film the 23-foot long shark.

Perrine evoked memory of his encounter with the Greenland shark, which dwells nearly 2,000 feet below the surface where water is less than one degree Celsius, to the Daily Mail.

I was amazed because most sharks are very shy of divers and tend to avoid the sound of scuba bubbles, but these these were attracted to the sound. They even swam closer to investigate. he told the Daily Mail. These sharks were very placid and curious. They are much calmer than other sharks -- they have an almost goofy, comical appearance.

In photos snapped by Perrine, the Greenland shark almost seems like it is smiling at the diver. Fascinated by his sighting, Perrine proceeded closer.

When I moved in closer to get a better shot, they did not flee but continued on their way at a steady pace, he said. The sharks were able to satisfy their curiosity about me by approaching to the limit of visibility at about six metres distance.

At just a few feet away, Perrine said he was not afraid of the creature, though it has a reputation for eating entire polar bears and reindeer.

The sharks are known to prey on large seals but I never felt threatened, Perrine said, adding the Greenland sharks swim in quite a lazy fashion.

Perrine founded SeaPics.com, an outlet to showcase his own marine photography along with photos from others. Perrine was named BBC Wildlife Photographer of the Year in 2004 and has shark photographs featured in Sharks of the Deep Blue on Discovery Channel's infamous Shark Week in 1999.

While Perrine was merely frolicking to snap their photo, Greenland sharks are typically hunted by residents of Iceland and Greenland in order to make boots from their skin and Hakari, the national dish of Iceland, from their flesh.
