On Sunday evening, the Discovery Channel aired its heavily trailed Eaten Alive show, which involved American naturalist Paul Rosolie being eaten alive by a giant anaconda.
For the stunt he wore a special protective suit to allow him to survive being eaten and digested by the snake.
Towards the end of the show the anaconda was shown biting Rosolie's helmet and wrapping itself around him.
The snake's crushing power proved to be too much for Rosolie and his protective suit and the stunt had to be called off before it tried to swallow his head.
The Daily Mail quoted him as saying afterwards: "The last thing I remember was her mouth open wide and everything went black.
Some viewers though were pretty unimpressed by the fact that Rosolie wasn't actually eaten alive and on Sunday evening Twitter was full of people complaining that a human being hadn't been consumed by a giant snake for their entertainment.
