Wince-inducing footage has been shared online showing the impaled reptile writhing in pain as bright white spikes protrude from its body.
At one point the snake attempts to curl its neck around to remove the prickles from its skin.

The hungry snake seemingly came off worst after trying to feast on the porcupine, which fought back with its quills.
Following the prickly experience, the reptile was then confronted by a barking dog who is seemingly confused by the snake’s strange spikes.
After almost two excruciating minutes, the boa constrictor finally curls up in a ball.
The clip was filmed in an unknown location in Brazil and has since racked up thousands of views after it was posted on video-sharing site LiveLeak last week.
One user wrote: “Help the poor thing.”
Another posted: “Bad day for the snake. I’d mercy kill it.”
But a third saw the funny side, writing: “I think the snake learned its lesson. Haha.”
