A doorbell camera captured the moment a huge snake plunged its fangs into a man's face when he opened the door to his friend's home.
Jerel Heywood was attacked by the reptile when he arrived at Rodney Copeland's house in Lawton, Oklahoma, USA.
Rodney said he was shocked when he saw the creature, which was wrapped around a porch light, bite his pal, according to reports.
The camera footage shows Jerel leaping back immediately after the attack, before moving into the home.

Rodney told CNN his friend was shouting and clutching his face when he staggered into the property.
He added: "I was in shock. That could've been anyone of us."
Jerel immediately feared that the snake might be venomous and Rodney and his wife took him straight to hospital.

However, doctors informed him the bit was not poisonous and that he would be alright.
He said: "No stitches, thankfully, but they cleaned me up pretty good. I am on antibiotics."
A neighbour rushed over Rodney's home with a hammer, after hearing the commotion, and knocked the snake off the porch light.
He then beat the reptile, thought to be 5ft 5ins, to death.
It is believed that the creature was taking refuge from heavy rains in the home.

Oklahoma has 44 native snake species, of which only seven can cause harm to humans.
Snakes usually only attack people when they have been disturbed or provoked.
