Amusing footage of a territorial fish attacking a snorkeler's GoPro off the coast of Mystery Island in the South Pacific.
The video, filmed on Monday, shows the fish protecting its little home in a reef by repeatedly charging at the diver's camera in crystal clear water.
The filmer later wrote online: "While snorkeling off Mystery Island, I felt something attacking my flipper.
"I turned around to see what it was and this small black fish started darting in and out of its coral hideaway and attacking my GoPro."
"I'm not sure what type of fish it was, but it was very tenacious, so after a short while I left it alone," he continued.
