If you're traveling to the East, anywhere from India to Taiwan, be sure to make a mental picture of the snake in the photograph below and STAY AWAY.
My theory is to stay far away from all snakes, but the Russell's Viper is known as one of the most poisonous snakes in the world.
These snakes tend to stay clear of cities, but out in farmland, they are abundant.
Growing to be about 5 feet long, just one untreated bite can lead to death in humans.
These snakes reproduce like crazy; a female can lay as many as 25 eggs at a time!
