Xenodermus javanicus (Javan mudsnake) 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. The Javan mudsnake is both feared and worshipped by communal Japanese.

Differentiation of Sex Chromosomes and Karyotype Characterization

Although most snakes have a karyotype with a stable chromosomal number of 2n=36, the Xenodermus javanicus has an unusual chromosal number of 2n=32. Heteromorphic ZZ/ZW sex chromosomes with a heterochromatic W are present in the Xenodermus javanicus.[1]
