The Malayan pit viper has an average size of 60 – 100 cm with a moderately stout body. This species usually stays in the leaf litter and can camouflage in fallen leaves in order to catch unsuspecting prey, avoid being seen by its predator and will flatten their body when they felt threatened. The colouration background across the vertebral ridge is varied from pale, greyish or reddish brown with dark brown saddles. The Malayan pit viper’s head has nine prominent, symmetric, unfragmented head shields. The head is dark with white upper lips scales and the white line from its eyes extending to the base of its jaws. It is a highly venomous snake and organs of the pit are present in front of the eyes (Sibunruang et al., 2013). The 13-20 cm long hatchlings are similar to the adults except for their bright yellow tail, which is elevated and moved to lure its prey.
