Arteval Duarte, from Brazil, wrapped a cat-eyed snake around a pinktoe tarantula before placing them in his mouth in a bizarre new video.
Mr Duarte says he has been charming and training poisonous animals for more than 15 years.
Just one sting of the tarantula can cause necrosis.
Fortunately for the creatures, they are only in his mouth for a few moments before they fall harmlessly out.
