Belize does have snakes this long. I ran over one on the coastal road many years ago. We could feel the "bump" as we passed over it! We stopped to look back and it was still moving along.....
The guides here say it's a Wowla, probably a kriol name for big constrictor. They eat monkeys, coatimunda and wild pigs. ..and get to be 15 to 20 feet long. I have not seen one but the Guides are saying 'Yes', the photo is probably real.
