Bicoloured Reed Snake  -  Calamaria bicolor
   
   

Family : COLUBRIDAE
Species : Calamaria bicolor
Maximum Size : 45 cm

This small, brightly coloured snake (with an estimated total length of 13-15 cm) was found near a stream in a forested area of North Kalimantan, Indonesian Borneo, at an elevation of no more than 300 metres, by Mr. William Bruce.

Its body colour is orange-red, and it bears around 35 narrow dark bars which are equally spaced along the body and tail.

The snake has been identified as a juvenile Calamaria bicolor by Mr. Björn Lardner.

Calamaria is a genus of terrestrial or fossorial snakes which are typically found after dark on the forest floor. They feed mainly on soft-bodied invertebrates.
