Alligator bites off the arm of a Florida teenager

A vicious, 11-foot alligator has bitten off a Florida teenager's arm, BBC News reported. Kaleb Langdale, 17, was flown to a hospital and survived the attack.

Langdale had been swimming at the Caloosahatchee River in Florida with his friends. His friends say that the alligator then came out of nowhere and lunged at Langdale, WBBH reported. "It took his arm and took him under," a witness told the station.

Langdale disappeared under the water, then quickly popped back up. "He was waving saying, 'Call the paramedics! My arm is gone!'" a friend told WBBH.

After the attack, the Florida Fish and Wildlife Conservation Commission found the arm–inside the alligator's body. They had to retrieve the arm by killing the alligator and dissecting it, the Associated Press reported. The arm was flown to the hospital, but doctors were unable to reattach it.

The river is known to have several large alligators, especially during this time of year. But it's rare for wild alligators to actually bite people. A Florida Fish and Wildlife Conservation Commission spokesman told the AP that "anything that makes any splash in the water or any little commotion in the water may attract them to that particular location."
