Woodpeckers avoid brain damage with their tongues

Woodpeckers endure forces up to 1,000 times the acceleration of gravity with each peck, yet avoid brain damage. Their secret lies in a unique tongue structure. A long hyoid bone wraps around the skull, acting like a seatbelt to absorb and distribute shock from high-speed impacts. This cushioning effect prevents concussions, protecting their brains from repetitive hammering. This amazing adaptation also allows them to extend their tongues up to four inches to catch prey.
