The same shark attacks 4 swimmers on South Padre Island in Texas

It was like a scene from Jaws.

A single man-hungry shark attacked four swimmers enjoying the Fourth of July on a Texas island, leaving at least one victim with a bite-shaped chunk missing from his calf.

Horrifying footage of the aftermath shows the giant predator stalked along the shore while a profusely bleeding woman lies helpless in the waves of the Gulf of Mexico on South Padre Island.

Screams of pain can be heard as passersby hastily apply a makeshift tourniquet below her knee – just inches from where the shark sank its teeth into her flesh.

The woman was one of two people bitten by what is believed to be the same shark. A man was severely bitten in the leg around 11 a.m., officials said.

The man’s father-in-law said he saw the victim suddenly being pulled underwater.

“I swam toward him and he jumped out of the water and shouted, ‘Shark, shark, shark.’ The adrenaline was pumping through my veins. I swam after him,” Rayner Cardenas told KRGV.

Two other swimmers “encountered” the shark but were not seriously injured, Texas Parks and Wildlife officials said. One suffered only minor injuries, while a man fought off the shark and required stitches.

Investigators suspect that the same shark is responsible for the “abnormal and unprecedented” attacks.

The man-eater has now fled to deeper waters and the authorities have no plans to capture this apex predator, but are monitoring the coasts with drones.

This wave of attacks is the first in the region five years ago.

“Encounters with sharks of this type are not common occurrences in Texas,” officials said in a statement. “When shark bites do occur, they are usually a case of mistaken identity by sharks searching for food.”

Authorities have advised beachgoers to “watch for large schools of bait near shore, as this is usually an indication that a predator is nearby. If you see a shark in the water, you should calmly exit the water and wait until the predator has passed.”
