Certain species of rattlesnakes have skin structures that allow rain to accumulate and coalesce on their skin to harvest as drink , but I’m seeing it for the first time in a western bush viper, a venomous snake found only in the forests of west Africa 1/

Some species of rattlesnakes have nano channels at just the right depth, that form a labyrinth-like network on their surface to capture water. Perfect adaptation in arid environments to collect water rather than travel long distances to watering holes 2/
