Feature Facts

  • This species was discovered and described  relatively recently (1989-1990)
  • Like other pit vipers, has special infrared-sensing pit organs to "see" their prey's body heat (warm-bodied mammals); pit organs aid in detection of prey and help guide a strike
  • Venom degrades in sunlight; melanin accumulates around this viper's venom glands to prevent damage to venom
  • Most pit vipers give live birth, but the Mangshan pit viper lays eggs.
  • Little known about many aspects of this animal's biology, including its growth, behavior, and reproductive biology
  • Occupies a small range in China
  • Major threats include illegal hunting and pet trade, logging of forest habitat, and climate change
