Giraffes sleep only 30 minutes a day

Giraffes are masters of minimal sleep, often resting for just 30 minutes daily in the wild. This extreme brevity is a survival tactic against predators like lions and hyenas, as their towering height makes them easy targets. They take quick, shallow naps, sometimes standing or with their heads on their rumps, always ready to flee. While captive giraffes might sleep longer, wild ones prioritize vigilance. This adaptation highlights how evolution favors survival over rest in dangerous environments, allowing them more time to forage for acacia leaves.
