A snake expert live-streamed his excruciating death over the internet after he let his pet black mamba bite his hand.
Arslan Valeev was apparently brokenhearted following the breakup of his marriage and pleaded with horrified viewers to call his ex-wife.
His condition deteriorated as the harrowing scenes were broadcast online.
The 31-year-old's breathing quickened and his eyes started rolling before his limbs appeared to become numb from the deadly snake's venom.
Arslan and his wife Ekaterina 'Katya' Pyatyzhkina were famous for running YouTube channels about snakes and cats, with hundreds of thousands of followers.
The actual snake bite and moment of death were not shown, but the Russian video blogger and former zoo employee showed off the bite on his hand.
At the end of the footage, he got up from his chair and staggered off camera. He died soon afterwards.
Friends said that Arslan had accused his wife of cheating on him, while reports claimed he had beat her and she had suffered a concussion.
Last week, Arslan publicly apologised to her for his behaviour, but she had already obtained a divorce and was in a new relationship.
In the shocking live stream, he said: "Hi. So, guys. It's time to do what I must do. Live stream [unintelligible]."
He then got up and went off camera, but a muffled sound of "ouch" could be heard as the deadly snake bit him.
He returned telling viewers: "If I die, then I die."
