Green vine snakes?
Ahaetulla nasuta
and
Ahaetulla mycterizans
I think they are just awesome but I cant seem to find anything in books about there bites. I got 3 books and all have them in it, one talks about care and handeling but nothing about how deadly they are or if not. and all 3 books are from the late 70s to mid 80s... :(
EDIT: I did alot of web shearching and couldnt find a thing... any care pages or info was mostly in german and frinch and any english pages just showed photos and natural history.
