THIS is the terrifying moment a gargantuan shark bites an aquarium mermaid’s hand, filling the tank with blood and leaving her needing 100 stitches.

Footage shows the victim wiggling her mermaid tail before the shark nearly rips her arm off clean.

The mermaid, Ms Li, is now filing a lawsuit for compensation following the horrific incident that took place in 2023 in Jiangsu, China.

Incredible video shows her swimming in the aquarium as she prepared for a mermaid competition when a shark suddenly attacks.

The mermaid desperately pokes the monstrous creature in the eyes and its head until it eventually lets go of her.

She quickly swims to the surface, with a second clip showing her blood-soaked injury.

Ms Li said that the shark had poor eyesight and may have mistaken her arm for fish food – or may have been frightened.

She was rushed to hospital and had to undergo a horrific, five-hour operation.

Ms Li suffered a wound so deep that her bone was exposed, and medics unbelievably recovered a shark tooth during surgery.

The victim had to receive over a whopping 100 stitches after the ordeal and was diagnosed with a grade 10 disability.

This is because a tendon, radial artery, and radial vein were all severed in the shark savagery.

Following the attack, despite Ms Li recovering well, she has little to no feeling left in her hand.

This injury has led her to sue the aquarium.

After failing to reach an arrangement with the aquarium regarding compensation, she filed a complaint against them.

The Binhu District People’s Court of Wuxi City decided that the diving project’s operator should take 70 percent of the responsibility, while Ms. Li was found to be 30 percent responsible.

The court stated that Ms. Li had signed a waiver, possessed a diving license, and did not adequately pay attention to her surroundings for her safety.

But the aquarium was also found guilty of failing to meet safety standards.

The Sipadan Company, which operates the aquarium, was ordered to compensate the mermaid around £14,342.49.

Ms Li said that this case is the first of its kind in the country and said that the main cause of the accident was negligence on the part of the operator and was therefore unsatisfied with the verdict.

She said: “This accident could have been avoided. I just hope that the other party can bear all my medical expenses.”

Ms Li plans to appeal.
