Snakes sense of smell

Snakes use smell to track their prey. It smells by using its forked tongue to collect airborne particles then passing them to the Jacobson's organ or the Vomeronasal organ in the mouth for examination.^[32] The fork in the tongue gives the snake a sort of directional sense of smell and taste simultaneously.^[32] The snake keeps its tongue constantly in motion, sampling particles from the air, ground, and water analyzing the chemicals found and determining the presence of prey or predators in its local environment.^[32]
