What is the Jacobson's organ in reptiles and amphibians?
Quick Answer
The Jacobson's organ, also called the vomeronasal organ, helps many reptiles and amphibians detect chemical cues in the environment.
The Full Story
The Jacobson's organ is a specialized sensory structure used to process pheromones and other chemical signals. Snakes and lizards often sample the air and ground with their tongues, then transfer particles to this organ for analysis. In amphibians, chemical sensing also plays a major role in communication, predator detection and mate finding, though the anatomy varies by group. This system gives many reptiles and amphibians a powerful sense of smell-like chemical awareness.
