that is so Gross ! who would eat a Guinea pig !
The green one is a vine snake. Rear fanged colubrid. The venom isn't thought to be too bad. While there a guy was bit and except a bit of numbness around the bite, he was fine.WOW! Those are some awesome pictures! What kind of snake was the green one? Looks fairly dangerous to me. You must of had a great trip. Thanks for sharing those photos.
