ok so lets see how we go with this one. I already know what it is but this group can be troublesome especially without locations...so its from Australia. What is it and more importantly why????
ok now secondly, there are a few on this site (that don't need to be named) that are more than apt when it comes to id....for those instead of posting what it is in the thread shoot the answer in a pm and I will confirm or discard it and save the answer coming up in the first hour or so to give people a chance to work through the id rather than saying its a ....+1 etc
I can provide a few of these testers if you like but feel free to add one once the id of the critter is confirmed (in this initial case by me).
Hopefully this will provide so intelligent discussion (so unless it actually is a Tropidonophis lets refrain from saying its a false clarence river snake aka kb)
