What is the primary purpose for a snake having a forked tongue?
Answer To detect chemicals in the air from two points providing "depth perception"
Snake tongues have the ability to detect chemicals in the air, much like our sense of smell. Having a forked tongue enables them to detect the smell from two points giving them a depth perception, similar to that provided by our eyes.
