This snake isn’t seen that often in Thailand, but they are common enough. I’ve seen three in the wild and this one that friends already caught.
This is a paradise tree snake – Chrysopelea paradisi, a flying snake. They can glide very far when they jump from high trees. Very far as in tens of meters horizontally. There are other flying snakes that are similar – and you’ve probably seen them – they are much more common…
Here is one ->
Flying snakes are not very dangerous. I’ve been bitten by them many times, and never had anything come of it. That isn’t to say you should let one bite down on you for many seconds though. They do have venom, they have rear fangs which inject venom into small pray like their favorites – geckos and frogs. The venom works well on those smaller creatures, but you’ll probably not notice anything if one bites you.
If you have any snake ID questions, go to ThailandSnakes.com and choose the link in the upper right about ID’ing snakes. Fill out the information and send me a photo to: email@example.com. I’ll see if I can figure out what it is.
