Forked tongue
The head of a Coastal Carpet Python, the largest subspecies of Morelia spilota, a non-venomous Australian python, showing its forked tongue, a feature common to many reptiles, who smell using the tip of their tongue. Having a forked tongue allows them to tell which direction a smell is coming from.Photo credit: LiquidGhoul
