A new video has been released this week showing why you don't want to mess with a Great White Shark.

In a video taken in 2013 by the REUMS SharkCam, an underwater research vehicle used underwater by the Woods Hole Oceanographic Institution, a shark can be seen attacking the specially equipped underwater vehicle as if it were lunch.

The autonomous underwater vehicle's (AUV) main task is to track sharks that have been fitted with transmitters and then follow them, according to the Institution.

Researchers never expected that any of the sharks would react in a violent way like one Great White did recently.

"Hitchcock would have been very proud," said Roger Stokey, a senior engineer at Woods Hole who was on the boat when the attack occurred, according to The Boston Globe.

Luckily the REMUS camera isn't too damaged and will continue to tail and observe the fearsome hunters.

The REMUS SharkCam is a specially outfitted REMUS-100 autonomous underwater vehicle equipped with video cameras, navigational and scientific instrumentation that allows it to find, track and film tagged marine life.

The vehicle is pre-programmed to home in on a signal from a transponder beacon attached to an animal at depths of up to 330 feet.

The REMUS SharkCam has been tested on white sharks and basking sharks near Cape Cope and on white sharks near Guadalupe Island on the West Coast of Mexico.

Missions can last up to 8 hours long, according to the Institution.

"We had a vague notion something was going on," Stokey said. "We were absolutely dumbfounded. We thought it was a machine and the sharks would have had no interest. There are a lot of fish that size down there. Clearly they thought it was something good to eat."

Eventually the institution plans to use a system to track other large marine life like seat turtles.
