In a dramatic video, the huge reptile is seen slithering alongside the mammal’s carcass.

Several people stand around as they watch the attack unfold.

Without warning, the snake begins swallowing the deer’s head before casually sliding up its body, reports the Sun.

The fallen beast’s limbs are then chomped down and within just 10 seconds of starting its feast, the carcass is consumed.

A brave man casually taps the snake on its body before the clip comes to an end.

Since being posted on Reddit earlier today, the clip has gone viral.

But eagle-eyed viewers spotted something not quite right.

‘I thought the people touching the snake was weird - I’m pretty they don’t like being touched just after they ate,’ one wrote.

Another responded: ‘They don’t swallow food this quickly.’

‘This video is a reversed video of a snake regurgitating a large meal when it was confronted with humans who scared the snake and caused it to vomit up its stomach contents to allow it to move quicker and escape.’

But a third was still stunned by the snake’s speed, saying: ‘I didn’t know they worked so fast.’
