The brown, or purple kukri snake inhabits lowland and lower montane forest, including secondary forest, to an elevation of around 1200 metres.
The species is described in the literature (Das, 2010) as being nocturnal, however the images presented here are of a specimen encountered late morning in bright sunlight. As with other kukri snakes, the species is fully terrestrial.
This snake feeds on a variety of other vertebrates including frogs, lizards and their eggs. It is also known to feed on birds eggs, presumably of birds nesting on or close to the ground.
It has a moderately robust body, with a short head which is no wider than the body. Its body colour is generally brown, becoming purplish with age, and is patterned with a series of equally spaced dark brown bands across the dorsum, which are black-edged, and typically with a wavy margin. Between these bands are additional narrower, indistinct dark crossbars.
There is a distinctive pattern of dark brown bands on the head which includes a forward-pointing chevron on the nape and on top of the head, and another band passing through the eye (though a similar feature occurs in many other species of kukri snake).
The underside is pinkish or yellowish with dark, squarish markings at the edge of most of the ventral scales.
There is a rare colour form in which the upperside is red, with yellowish, dark-edged crossbars.
The brown kukri snake ranges from southern Thailand through Peninsular Malaysia and Singapore, to the Riau Archipelago and the islands of Sumatra, Borneo and Java. |
