Sunda Island Pit Viper (Trimeresurus insularis)

The Komodo dragon is not the only animal in Komodo Island that makes me visit over and over again. This snake has always been the second sought-after species in my previous trips to Komodo Island.

The Sunda Island pitviper (a.k.a. Lesser Sunda Island pit viper, White-lipped island pit viper, or Blue insularis viper) is native to Komodo and some nearby Indonesian islands such as Bali, Flores, Lombok, Padar, Rinca, eastern Java, Adonara, Alor, Romang, Roti, Sumba, Sumbawa, Wetar, and also Timor of East Timor.

Although mostly turquoise or blue, some snakes of this species can be bright green or bright yellow. Interestingly, some blue individuals are born green and turn into blue in a year or two. No doubt, this species has the most outstanding colors of all 50 species of Asian pit vipers (Trimeresurus) while 90% of the species in the genus are green such as the Bamboo pit viper. A few species are very dark to almost black such as the Mangrove pit viper.
