Overview
The jasper cat snake is a moderately sized, arboreal member of the genus Boiga distributed across parts of Southeast Asia. Its name derives from the mottled, marbled pattern of its scales, reminiscent of the jasper mineral.
It inhabits lowland forests and is a nocturnal predator, though it is considered a relatively uncommon and less frequently studied species within its genus.
As a rear-fanged species, it is mildly venomous, with bites that are not considered dangerous to humans.
How to identify it
- Slender body with a mottled, marbled pattern of browns, tans, and grays resembling jasper stone
- Broad head distinct from the neck, with vertically elliptical pupils
- Smooth scales
- Pale venter, often with mottled markings
- Long, tapering tail suited to climbing
The marbled, jasper-like patterning helps distinguish it from cat snakes with more clearly defined blotches or bands.
Habitat & range
Found in lowland tropical forests of Southeast Asia, including parts of Malaysia, Indonesia, and Borneo. It is arboreal, favoring dense vegetation and forest canopy.
It is thought to prefer relatively undisturbed, humid lowland forest habitats.
Behavior, diet & reproduction
Nocturnal, becoming active at night to forage among trees and shrubs. Its behavior is presumed similar to other Boiga species, relying on stealth and a mildly venomous bite to subdue prey.
Its diet likely includes small lizards and other small vertebrates. It is presumed oviparous, though detailed reproductive information is limited due to its infrequent study.
