Scientists with a marine life protection non-profit captured a 2,000 pound great white shark for their experiments and then released the ocean beast back where it belonged.

That was the third time Ocearch researchers caught a shark and pluck a tracking device in it. Mary Lee, a 16-foot, 3-500-pound was the first shark to be caught and tagged; followed by Genie, 14-foot, 2,300-pound – all of which took place last September off the coast of Cape Cod. The recent capture was baptized by the name of Lydia.

The recent capture took place Sunday near Jacksonville, Florida. Before gaining control, the 2,000-pound 14.5 foot long killer dragged the scientists and their boat in reverse after chomping down on the chum, which is a bloody mix of various fish guts used to attract sharks in the open water. Once the scientists had the shark secure, they tagged a GPS device to her fin, took several blood tests and ran an ultrasound that denied any hopes of pregnancy before releasing her back to the ocean, according to Huffington Post.

Great white sharks are some of the most fearsome predators of the deep. Now, scientists are aiming to learn more about white sharks’ migration patterns along the east coast to help protect breeding grounds of those creatures which are slowly disappearing from the world's oceans

Despite the great white's terrifying reputation, Ocearch is concerned with the species' declining population. The great white is currently listed as "Vulnerable" on the IUCN Red List of Threatened Species. This is concerning since the shark is imperative to maintaining the health of marine ecosystems as the ocean's top predator, according to the Endangered Species Coalition. Unfortunately, sharks are killed every day, and through their research, Ocearch hopes to affect policy for global change.

For those interested, Ocearch keeps a life stream on its website of all its tagged sharks. But beware, some of the GPS signals come alarmingly close to shore. Perhaps someone afraid of the deadly killers could take refuge in knowing their current location, but if they swim too close to home, they may think twice before jumping in the water.
