Bornean Short Python

Adults of P. breitensteini have been reported to attain a total length (including tail) of 2.1 m (7 ft), although they are usually no more than 1.2 m (4 ft). Heavy-bodied, they can weigh as much as 13.6 kg (30 lb). Females are generally larger than males. The head is broad with several thermoreceptive pits along the nose. The tail is short and tapering. The color pattern is usually tan with brown blotching, which varies greatly. Though no instances of albinism have been reported, a few individuals display a significantly lighter color, appearing more yellow than brown. Juveniles have a more contrasting pattern than adults. The head is usually yellow.

On the island of Borneo, P. breitensteini is found in Brunei, Indonesia, and Malaysia. Typically, it is found at lower elevations, on poorly drained flood plains, or on the edges of swampy areas; man-made irrigation of farmland has also provided appropriate habitat.
