Wagler's Pit Viper (Tropidolaemus wagleri) is a species of venomous pit viper and some of the largest and heaviest arboreal vipers found in Thailand. Sometimes it is referred to as the temple pit viper because of its abundance around the Temple of the Azure Cloud in Malaysia. (This snake looks a lot more green and the Malaysian one has more yellow on them.) This snake is highly venomous. The full length (including the tail) of the female is approximately 1 m (39 1⁄4 in), twice the size of males. 

Female Wagler's Pit Viper differs greatly in appearance to males, which are green. It's just so incredibly pretty, arguably the most beautiful as well. It has a beautiful huge triangular-shaped head and a relatively thin body with very green appears across its spine. It is really distinct because its neck goes pretty thin and the head is super bulging out.

Unlike a lot of smaller pit vipers, the wagler's pit vipers have much more heavy body, meaning that they only rest on branches which are a lot thicker in order to support their body weight because they don't want to risk like getting blown down by the wind or something.  During more drier months they tend to go higher in the trees.

Wagler's pit viper is famous for being one of the calmest viper species you can find. It remains motionless for long periods of time waiting for prey to pass. It will sometimes sit on a large round ambush for weeks without moving. When prey like geckos, birds or rodents do pass by, or if disturbed, it will use these horizontal branches as a pathway to get from tree to tree, and strikes quickly.
