A shocking video has emerged of Brazilian activist Arteval Duarte getting bitten by a snake during a stunt in July.

The footage, shot in Jacunda, Brazil, shows the 'Ninja of Serpents' getting bitten by the large snake as he tries to put its head in his mouth where he already holds a tarantula.

His face is left covered in blood, but he doesn't seem to mind all that much.

Arteval regularly performs stunts like this to raise awareness about deforestation in the Amazon. Sometimes, they go wrong.
