One of several Bamboo Vipers found on steep hillsides in Karnataka, India, a couple of years back.
A Malabar Pitviper from southern India a couple of years ago on a wet night in the Western Ghats. After seeing a few of them, the convergent similarities in form and behavior with new world vipers, like the eyelash vipers, is amazing.
