Fancy a dip? Snorkelling with a dozen hungry sharks looks insane

This is the moment some brave snorkellers took to the water surrounded by a dozen hungry sharks.

In the clip, which was filmed earlier this month in the Bahamas, the 2.5-metre reef sharks swirl around the water looking for food, just inches from the snorkellers.

Although it might look dangerous, the video was captured under the supervision of professionals and shark behaviour specialists who are taking part in a programme to promote shark conservation in the Bahamas.

"Such beautiful creatures," said filmer Chad Sinden who owns a local dive centre.
