Oreocryptophis

Oreocryptophis is a small genus in the family Colubridae, the largest and most diverse snake family in the world. The genus is best known for a single widely recognized species, Oreocryptophis porphyraceus, the red bamboo ratsnake, sometimes also called the red mountain ratsnake. It was long placed in the broad Old World ratsnake genus Elaphe before being separated into its own genus, and that history tells you where it sits: among the typical nonvenomous Asian ratsnakes, slender egg-laying colubrids with smooth scales and round pupils. Several distinct regional forms are often treated as subspecies, which is why the snake looks somewhat different from one mountain range to the next. The Red Mountain Ratsnake is the member represented in our database.

This is a snake of cool, forested uplands rather than lowland heat. Its range stretches across montane parts of South and Southeast Asia, from the Himalayan foothills and northeastern India through southern China and into mainland Southeast Asia, with related forms reaching further south on the Malay Peninsula and nearby highlands. Typical habitat is humid mountain and submontane forest, often at moderate to fairly high elevation, where it shelters under leaf litter, logs, and forest debris. It tends to be secretive and most active in the cooler hours, which keeps it largely out of sight. In general terms it is a slim, moderately sized snake, usually well under about 1.5 meters, with smooth glossy scales and an often vivid pattern: warm orange to reddish or pinkish ground color crossed by darker bands or marked with bold dark longitudinal stripes, the exact look depending on the regional form.

The red bamboo ratsnake is nonvenomous and harmless to people. Like other ratsnakes it overpowers prey by constriction rather than venom, and it poses no medical danger to humans, though any wild snake may bite defensively if cornered or grabbed and is best observed from a respectful distance rather than handled. Ecologically it is a constrictor that feeds chiefly on small mammals such as rodents, the kind of diet typical of ratsnakes across this family, and like most colubrids in its range it reproduces by laying eggs. Its preference for cool, damp, shaded forest floor, combined with its retiring habits, makes it a quiet and uncommonly seen resident of the Asian highlands.
