Ok please can you help me ID this snake? The person wanting to sell it insists that it is Elaphe taeniura friesi (Taiwanese Beauty Snake), and for all intents and purposes, it seems to look like the photos of the Taiwans... However, I read that they are NOT supposed to have blue tongues, that they are the exception of beauty snakes which have blue tongues, but the taiwans have red tongues. I am not sure if this info is correct though. So is this a Taiwanese Beauty Snake? Or is it another beauty snake like the yunnan?
