Lesser Sunda Islands pit viper, Sunda white-lipped pit viper
The color patterns of Indonesian pit vipers are often found to be green or a blue-green color with specific populations even containing yellow variants as well. The scalation includes 21 rows of dorsal scales at the midbody, 156–164/156–167 ventral scales in males/females, 70–75/54–59 subcaudal scales in males/females, and 7–12 supralabial scales.
These snakes are found in East Timor and in Indonesia in eastern Java, Adonara, Alor, Bali, Flores, Komodo, Lombok, Padar, Rinca, Romang, Roti, Sumba, Sumbawa, Timor, and Wetar. They inhabit dry monsoon forests, and tropical moist forests and can also be found in rural gardens.
Indonesian pit vipers are arboreal and spend all their lives in trees. They hunt by night waiting patiently on a branch usually several meters above the ground. They like to hide between the foliage, relying on their great camouflage. If disturbed or approached too close Indonesian pit vipers will take a S-shape posture, open their mouth, and may even bite.
Indonesian pit vipers are carnivores that feed on various arboreal rodents, lizards, and small birds.
Indonesian pit vipers are ovoviviparous meaning they give birth to live young.
This species is highly abundant across its native range and doesn’t face any major threats at present.
The IUCN Red List and other sources don’t provide the number of the Indonesian pit viper total population size. Currently, this species is classified as Least Concern (LC) on the IUCN Red List.
