Okapids are most active during dawn, dusk, and night. Their eyes are adapted to low-light conditions. Large pupils allow more light to enter, enhancing vision. This helps them navigate dense forest in near darkness. Night activity also reduces encounters with humans. It further enhances their elusive nature.
This adaptation allows okapids to exploit safer activity periods. Reduced competition and danger improve survival.
It demonstrates how sensory evolution shapes daily behavior. Timing can be as important as strength.
Okapids can detect movement in near-total darkness.
