Antelope horns are living radiators

Some antelope species, like the oryx, use their horns to cool down. These horns contain intricate networks of blood vessels that expand when the animal's body temperature rises. This increased blood flow turns the horns into efficient radiators, releasing excess heat into the scorching air of their desert homes. This clever adaptation allows them to forage during the day without overheating, highlighting how evolution creates multifunctional traits.
