Porn star model 'bitten' by shark during underwater shoot

A US porn star has been filmed receiving a bite to her ankle from a lemon shark off the coast of Florida - but there are doubts over whether the footage is real or just a publicity stunt.

Molly Cavalli, a model for porn website Camsoda, was filmed going into the water in a shark cage with a snorkel on for a video that was allegedly meant to showcase the website's new video technology.

However a live broadcast of the technology's debut was cut short when a lemon shark appeared to sneak through one of the very wide gaps in the cage and bite her ankle, leaving a gash.

"The underwater broadcast had to be cut short when Molly's foot stuck out of the cage and was bitten by a lemon shark," Camsoda said on the YouTube video's description.

"Don't worry though, Molly is doing just fine. She had to get 20 stitches, but she is in good spirits and grateful for her quick recovery."

Ms Cavalli doubled down on the shark bite tale, posting on Instagram and letting her fans know that she was "totally fine" and "healing quickly" from the gash, which she claims is "not as bad as it seems".

However a shark expert has expressed doubt that the footage is real, telling Yahoo News that lemon sharks don't tend to attack people and that the gash itself wasn't consistent with a shark bite.

Dr Samuel Gruber said while "the lesion looks pretty real", lemon sharks have very small teeth that are unable to produce the open wound seen on Ms Cavalli's ankle in the video.

While he wouldn't rule out the legitimacy of the video, Dr Gruber said there were aspects of the video "that look staged".
