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.

While snorkelling off Mystery Island (Aneityum Island, Vanuatu, South Pacific) 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.
Mystery Island was a stop over on a Carnival Cruise I went on and I can highly recommend the Island for snorkelling. The water was crystal clear, the coral was bright and colourful and the number and variety of living things was amazing.
