Snakes have something called Jacobson’s organ, which is basically two cavities inside their nasal area, where they actually insert the two tines of their forked tongues after having “smelled” by performing the characteristic tongue flick. They can then decipher the olfactory molecules of whatever prey they’re trying to track and be able to form a sort of 3d map in their head of where it’s located, provided it’s close enough of course.

Much like how having two ears allows our brains to spatially map out sounds in 3d. Thats really neat, I didn’t know that.
