Footage uploaded to YouTube shows the remains of the giant reptile chained to the back of a truck – and it's so big its folded to fit.

Information uploaded with the clip claims the creature slithered out of a cave AFTER construction crews building a dam rigged an explosion there.

And it said the massive predator weighed nearly half a ton, measured 32ft from end to end and was a metre across in places.

Now it seems the huge cobra could have been the largest snake ever, with bulges in its body clear signs of its voracious appetite.

While an official record is hard to come by, Guinness World Records lists the longest snake – measured in 2011 – as being eight feet shorter.

But the record holder, Medusa, is only the confirmed king of captive snakes, being owned by Full Moon Productions in Kansas City, Missouri.

The new discovery was reportedly found by builders at Brazil's Belo Monte Dam, which will be one of the world's largest on completion.

Sitting across the Xingu River deep in the Amazon rainforest, it has caused controversy because it will cause hundreds of square miles of flooding.

And construction crews are now under fire for not keeping the creature alive.Lucas Nunes said: "The guys in addition to destroying the habitat, kill the animal."

While William Santos wrote: "If it was a fisherman killing the snake, he took a fine, but as it is a large company, nobody does anything."

And Rulian Lopes Garcia said: "That's A crime. a large company like that should have people trained to handle such an animal. Since they are destroying his habitat."

The video of the snake was uploaded by Alexander Flores.
