(CNN) A woman was yanked from a boat when a shark she was hand-feeding bit into her finger and hauled her into waters off the northwestern coast of Australia.

Melissa Brunning was standing on the stern of a yacht, feeding fish to a group of tawny nurse sharks, when one sank its teeth into her finger and dragged her overboard.

Mobile phone video footage of the incident shows her screaming as she fell into the water.

"It happened so quickly. All I could really focus on was the fact that my finger is gone. He'd clamped on it and it felt like it was shredding off the bone," she said.

The attack occurred while the 34-year-old woman from Perth was on holiday in Dugong Bay, a remote spot known for its sharks and saltwater crocodiles.
