So... I've been going around some different places and I was told that snakes can benefit from UVB. They claim its a requirement. I am trying to figure out the reason behind this. If its for Vitamin D3 you can buy supplements to take care of that, correct?. I have tried to make a point that it is not needed, but I dont know enough to elaborate much more than snakes don't need it because they don't bask (Not all snakes. Garters come to mind.) Can someone PLEASE give me a more scientific and biological answer besides they don't bask?
