6. Watusi Cattle
Watusi cattle, tracing their lineage back to ancient Egypt, display majestic horns that can reach impressive lengths of up to 8 feet, with a circumference of 30 inches. Beyond their stunning appearance, these horns also serve a practical purpose. Blood vessels within the horns facilitate heat transfer, effectively acting as an internal cooling mechanism for the Watusi. This unique adaptation allows them to thrive in the blazing temperatures of African summers, showcasing the remarkable natural engineering of these extraordinary animals.
