Geckos' Inner Ear Reveals Hidden Vibrational Sixth Sense

Researchers discover that geckos use the saccule in their inner ear to detect low-frequency vibrations, altering our understanding of reptile sensory systems.

Geckos utilize the saccule, a part of their inner ear associated with balance, to detect vibrations between 50 and 200 Hz.
This vibrational detection complements geckos' normal hearing and might be present in other reptiles traditionally considered to have limited hearing.
The study suggests that reptiles previously thought to be 'deaf' may communicate through vibrational signals.
Findings provide insights into the evolutionary history of vertebrate auditory systems, highlighting gradual changes from aquatic to terrestrial environments.
Research may inspire further studies into mammalian hearing and the potential link between hearing and balance in humans.
