Snakes Read the World With Their Tongues

Snakes repeatedly flick their forked tongues not to intimidate, but to sample chemical cues from their environment. These collected particles are transferred to the vomeronasal organ, located in the roof of the mouth, for analysis by the brain. The tongue's forked shape provides directional information, enhancing the ability to pinpoint the source of scents.

This remarkable sensory system is utilized by various Indian reptiles, including the Indian cobra, common krait, and Russell's viper. These animals flick their tongues to gather information about prey, predators, and other snakes. The Bengal monitor lizard also employs a similar technique, demonstrating that this unique method of environmental reading extends beyond snakes.
