“We wanted to understand the chemistry of the outermost surface of the snake scales,” Weidner, who led a study presented at a recent virtual meeting of the American Chemical Society, told SYFY WIRE. “The composition of the snake tissue is very complex and has lots of different components. We were looking to see which of these components are actually present at the surface, where they play a role for friction and abrasion reduction.” Snake scales vary in surface chemistry depending on where that species lives and what kind of terrain it has to face. Weidner used laser spectroscopy and electron microscopy to study molecules on snakes whose bodies are in constant contact with surfaces from the ground to tree branches to desert sands. He zeroed in on the layer of molecules at the very top of the skin. These molecules all look spectroscopically similar, which is why surface-sensitive laser and electron methods can tell what kind of species they are observing just from the surface
