(Picture found here)
This made the rounds of UK newspapers a few days ago. It is allegedly a picture taken by an American hunter in Louisiana.
One commenter on the story says it's an advert for a computer game and cites the bottom-left tag 'Wildgame Innovations' as evidence. Nope. Wildgame Innovations is a hunting supplies company, not a games manufacturer. The picture appears under their 'success stories' listing, is taken using an infrared camera and was put there by someone who says it was taken by 'a friend of a friend'.
I am unconvinced.
First, if you were alone in the woods on a dark night, equipped for hunting, and that came at you - what would you grab first? The camera or the gun? I mean, it doesn't look as if that thing wants a conversation, does it?
Second, look at the arms. Huge shoulders with thin arms poking out of them. The musculature makes no sense. Its right arm has straight bones, its left arm has rubber bones. The right leg appears to be much thicker than the left.
My suspicion is that it was a photo that included an interestingly shaped object, perhaps a fallen branch, and that the head was added later. Or maybe it's a totally digital image.
Real? Not impossible, but I'd rate this as having no more than a 5% chance of being real. A second photo would improve that rating, preferably by someone completely unrelated to the first photographer.
Unknown large animals are certainly possible. There are many wild places on the planet where nobody ever goes. In recent years, a new species of ape has been found in Africa and it's only a few decades since the discovery of the giant and colossal squid species.
The thing in the picture, though, looks to have such odd musculature that it would be unlikely to thrive in woodlands. Its arms don't have enough muscle to be much use, it appears to have no fur or scales, its teeth don't look very big and its jaw isn't strong enough to rip through much of anything.
So, for now, I'd file this as 'not very likely at all'.
Unless someone else from Louisiana has seen one?
