Wagler's Pit
                   Viper


Wagler's pit viper is a medium sized viper, the male can grow up to 80 cm in length while the female can grow up to 130 cm in length. It is called a pit viper because they have pits just behind the nostrils which contain special organs that can sense heat and locate warm-blooded animals. This is an important adaptation since Wagler's pit viper is nocturnal and hunts at night.


Wagler's pit viper is an arboreal species, which means it lives on the trees. Wagler's pit vipers are ovoviviparous, producing eggs that are hatched inisde the body, so that the young are born alive but without placental attachment. The advantages of this is the eggs will be better protected than the eggs that are hatched on the ground. Wagler's pit viper has predators that keep watching them from the sky and the ground of Gunung Leuser National Park, one of them is the Crested serpent eagle & King cobra.




The heat-sensing pits that found in this snake made them named pit-vipers. These pits enable pit vipers to have what we would imagine to be infrared vision of heat wavelengths between 5 - 30 nanometers. Despite the fact of the long-standing belief that these pits evolved to function in detecting prey, the recent study believes thermoregulation and predator detection may have also contributed to the evolution of this complex sensory organ.




In hunting of prey, Wagler's pit vipers are always in a stationary position for the long term to find the right moment to ambush the preys with their haemotoxic venom. Tropidolaemus Wagleri is a venomous pit viper species native to Southeast Asia.




Picture above is the male, the male Wagler's Pit viper can be identified easily with its smaller size than the female, besides the difference in size, colour pattern and the body type is also quite different.



















Though the Wagler's pit viper is not considered as the aggressive snake species, but the Wagler's pit viper is specified as deadly carnivore, it means they are meat eaters. The venom of Wagler's pit viper attacks red blood cells and their ability to carry oxygen, the most dangerous thing from their venom is destroying the nervous system of the victims and also giving impact of burns. Wagler's pit viper preys on animals such as mice, lizards, birds and frog.

Study reports the Wagler's pit viper can be found in Southern Thailand, West Malaysia, Sumatra, Nias, and the isolated population in south Vietnam. Especially the Wagler's pit viper can be found in Gunung Leuser National Park, Bukit Lawang.
