Central Asian Pit Viper

Gloydius halys

Also known as Halys Pit Viper, Siberian Pit Viper, Halys Viper

Central Asian pit vipers rely on specialized heat-sensing facial pits to target warm-blooded prey in low-light environments. Perfectly camouflaged against rocky slopes and arid steppes, these adaptable reptiles spend early mornings basking before retreating to shade during midday heat. Females give birth to live young late in the summer, giving offspring immediate independence to hunt small lizards and insects.
