This sinister looking guy was creeping around in a tree near my tent in Kaeng Krachan National Park in Thailand. These green vine snakes are fairly common — and from what I’m told, only mildly venomous and not a significant threat to humans. I thought he was pretty cool looking with that arrowhead shaped pupil surrounded by white.
