A bizarre video has emerged of a man putting four tarantulas in his mouth in the Pará region, Brazil.

The footage, shot in a Brazilian farm near Jacundá, shows Arteval Duarte also known as the 'Ninja of Serpents' carefully putting four huge tarantulas in his mouth.

According to Duarte a bite from these spiders can cause harm but is not lethal.

Duarte says he performs these stunts to raise awareness about the deforestation of the Amazone and protest against the pollution of rivers.
