The first picture is of an Albino Dragon Snake. Xenodermus javanicus (The lower picture is a different morph)
Gorgeous snake! It took me a few minutes to find it, but it was definitely an interesting find.
"Javan mudsnake Xenodermis javanicus is a Colubrid snake found in South East Asia. It is noted for having large non-overlapping knobby scales of various diameters. The Javan Mudsnake has an enlarged head, heavily ridged scales separated by areas of much smaller scales, and an elongated tail. It is found in rice fields and feeds on frogs. They can reach to about three feet."
"Though discovered in 1846, this unique serpent, called Xenodermus javanicus by scientists, is very rare in the pet trade, and is still quite unknown, even amongst herpetologists. There is very limited information about this snake on-line or elsewhere, and its relative ambuguity, has led to several common names, adding to its mystery. Commonly called the Dragon snake, Javan Mudsnake and Tubercle Snake, this animal, found in Southeast Asia, and belongs to its own genus, meaning that it currently has no close relatives currently accepted by science."
......... I want one now LOL. Really pretty snakes, I was reading around a bit and someone was selling a pair for 5,000 a few years ago. Its husbandry though is pretty unknown so unless you find another species of snake living in the same region that shares similarities it'd be pretty hard to care for them properly. (Not like anyone would actually pay 2500 dollars for a snake that they practically know nothing about LOL)
