## Curiosity - Did you know?

For decades, scientists believed the tapering, cord-like tail could exceed the speed of sound and produce a deafening crack. Updated biomechanical simulations have thoroughly debunked this myth: a sonic boom would have destroyed the tail entirely. Still, lashing the air at 100 km/h, it remained an exceptional visual and tactile deterrent to disorient carnivores and communicate with the herd!
