A porn star taking part in a glamorous underwater photoshoot was bitten by a shark off the Florida coast after it broke through the bars of her shark cage.

The pornographic actress, Molly Cavalli, who was wearing just a swimsuit, had jumped into the shark cage to swim in the sea with sharks while the photographer took pictures.

But shortly after she got in the water, she was savagely attacked by a lemon shark that broke through the bars of the cage and took a bite out of her leg.
