Expert Answer:

Snakes have forked tongues so that they can smell in three dimension. Since the two tips pick up odors from slightly different locations in space, the snake can detect the direction of the source of the smell. If an odor is slightly stronger on the left tip, for example, the source must be somewhere to the snake’s left. So, whatever chemicals encountered in the prey, the two tips of the fork collects it and delivers into the vomeronasal organs which creates a stereo smell.
