Each okapi ear can move independently of the other. This allows precise sound localization in dense forest. They can detect predators without moving their heads. Ear rotation reduces unnecessary motion. This keeps them hidden while alert. It functions like biological radar.
This adaptation improves survival without drawing attention. Awareness does not require visibility.
It highlights how sensory control can replace speed. Listening can be safer than running.
Okapids can hear predators long before they are visible.
