It is a monotypic genus, containing only Xenodermus javanicus, also known as the dragonsnake, Javan tubercle snake, Javan mudsnake, or rough-backed litter snake.[2] It is considered to be rare.[3] (Though no conservation efforts are active.[4]) Xenodermus javanicus is the single representative of the genus Xenodermus and demonstrates unique external morphology, e.g. characteristic dorsal scales, among xenodermatid snakes, which facilitates their distinguishing from different species. The snake is fully nocturnal and subsists on a diet of frogs. Xenodermus javanicus is a small non-venomous, semi-fossorial reptile.[5] HabitatThe dragonsnake's natural range is Thailand, Burma, and Indonesia.[6] Dragonsnakes have been known to occur, at extremes, from southern Myanmar, southward to Sundaland (Sumatra, Java, and Borneo). (Although dragonsnakes only exist in Myanmar in marginal numbers.[4]) BehaviourBreedingDragonsnakes undergo reproduction by egg.[7] The dragonsnake is not considered to be a particularly prolific breeder.[4] SleepDragonsnakes are nocturnal.[8] DietDragonsnakes subsist mainly on frogs.[8] Human interactionDragonsnakes exhibit a peculiar property when encountering perceived threats. This action involves stiffening its entire body and straightening into a line.[8] Dragonsnakes are known to die when placed into captivity.[8] Conservation statusDragonsnakes are not the object of any conservation endeavours at this time.[9] References1. ^{{cite web | url = http://thereptilereport.com/dragon-snake/ | title = Dragon Snake | publisher = The Reptile Report}} 2. ^{{EMBL genus|genus=Xenodermus|date=13 January|year=2008}} 3. ^{{cite book |last=Rooij |first=Nelly de |authorlink= |title=The Reptiles of the Indo-australian Archipelago.
