Paraxenodermus

Paraxenodermus is a small genus in the family Xenodermidae, the odd-scaled snakes. The best-known member is the Borneo Red Snake, a rarely encountered species from the island of Borneo. The family as a whole is famous for unusual, raised or keeled scales that give the body a rough, almost beaded look, very different from the smooth, glossy scales of most snakes. Within this family, Paraxenodermus sits among other forest-floor genera like Xenodermus and Achalinus, all sharing a preference for damp, low-light habitats and a secretive way of life.

These snakes live in the wet tropical forests of Borneo, where they keep to moist leaf litter, stream edges, and the cover of dense vegetation. Odd-scaled snakes in general are tied closely to high humidity and are most active at night, which is part of why they are so seldom seen. In broad terms, members can be recognized by their slender, soft-bodied build and the distinctive rough or ridged scale texture characteristic of the family, rather than by bold color patterns. Their small size and reclusive habits mean most people will never cross paths with one in the wild.

Odd-scaled snakes are harmless to people. They are not venomous, they have no medically significant bite, and they pose no danger to humans. Their ecology, where it is understood across the family, centers on hunting soft-bodied prey such as earthworms, frogs, and other small forest animals in the damp ground layer. They are egg-laying snakes, and like many obscure forest species, much of their detailed behavior and breeding biology remains poorly documented. As with any wild animal, the right response to one in nature is to observe it and leave it undisturbed.
