SWIMMING along the surface, teenager Addison Bethea was on the lookout for scallops when she felt something tugging at her leg.
Expecting to see her half-brother Rhett, she turned around to look – and came face-to-face with a 9ft bull shark.
Addison, now 18, desperately tried to free herself from the terrifying beast as it tore at her right limb.
The high school student was saved by firefighter Rhett, who kicked the shark until it let go – then made a makeshift 4ft tourniquet to save her life.
Addison’s story features in a new BBC One documentary – Why Sharks Attack – which airs tonight.
