Super slow motion footage of a man putting his hand in the mouth of a particularly large alligator.

The video, filmed in April this year in Mosca, Colorado, US, shows a man wearing a GoPro camera on his arm touching the reptile's tongue.

The filmer later wrote online: "Elvis is almost 12ft long and the biggest and heaviest alligator at Colorado Gator Farm in Mosca Colorado.

"I got a new forearm mount for my GoPro and wanted to show people what it looks like to touch an alligator's tongue."
