Drone footage of a rather brave woman floating above a school of sharks off the Maldives has gone viral on social media.
Instagram user @shadowpalmmaldives, who recorded the video last month, said: "We go to snorkel with sharks. (On) that certain day there were a lot of sharks on the shallow ocean. She dared to float with them and then I took the shot."
Nurse sharks are generally harmless, but do bite defensively if stepped on or aggravated.
