Mangshan Pitviper

A medium-sized, slender pit viper typically measuring 24–31 inches (60–79 cm) in total length. Body is moderately slender with a distinctly triangular head set off from the neck. Dorsal coloration is bright green to yellowish-green, occasionally with scattered small pale flecks or spots along the dorsal surface. The head is predominantly green matching the body. A subtle pale vertebral stripe may be present along the midline. Scales are weakly keeled, giving a somewhat smoother appearance than many pit vipers. The tail is prehensile and may be slightly coiled, particularly in younger individuals, with a pale yellowish or whitish tip. Vertical pupils and prominent loreal pits are clearly visible. Ventral surface is pale green to whitish-green, sometimes with scattered pale markings. The rostral scale is slightly protruding. A key diagnostic feature is the small, discrete dark spot or marking on each scale of the body, creating a finely speckled appearance when examined closely. Inhabits montane cloud forests and forested slopes in subtropical to temperate regions at moderate to high elevations, often found in dense vegetation and among leafy branches where cryptic green coloration provides excellent camouflage. Typically encountered in cooler, mountainous terrain with high humidity. Diet consists primarily of small vertebrates, including lizards, small mammals, and occasionally birds, subdued via envenomation.
