Images posted by adventurer Bear Grylls of a gruesome snake bite sustained by his producer have gone viral.
Stephen Rankin was bitten by the "nasty and aggressive" Fer de Lance while filming Grylls' new show Naked and Afraid. The necrotising venom later ate through his skin exposing bone and tendons.
"It was under a fallen tree as I climbed over. Fer de Lance known to be aggressive and it just zapped me in the foot through my boot," Rankin tweeted.
He later posted another picture of the skin graft taken from his thigh which likely saved the foot.
