Thailand is home to a large variety of vipers. The majority are pit vipers that are easily recognized by the presence of a heat-sensing pit on each cheek.
At this point, the Siamese Russell’s Viper, Daboia siamensis, is the only viper in Thailand that lacks the heat-sensing pits. At the same time it is also arguably the most dangerous of all the vipers. Being terrestial, very well camouflaged, equiped with a highly potent, nasty venom, and living mostly in farm lands, it is like a living landmine.

The vipers are one of our favorite groups of snakes. There is just something about their usualy stout bodies, triangular heads and most of all the look in their eyes.

In the coming years the viper species list will likely increase quite a bit. We have seen various vipers that will likely be described as new species in the near future.
