Yeah that's nature photographer Daniel De Granville. He's on Facebook. He's got tons of amazing photos. He had a boa in his camp that kept coming back and he got photos of it catching and eating a monitor? I think? I'd have to look back at the photos to make sure what kind of big lizard it was but his photos are awesome.
Edit:: No wait! That's a different guy! Hang on.. Let me get one of Daniels photos.. This guy is really impressive with his work..
