There are more than a few animals with horns or antlers. These horns are used for mating purposes and they are also used as weapons for fighting. They let other animals know who is in charge because they are a sign of a higher ranking and they can help to keep the animal cool. They act as a natural radiator because of the blood vessels at the bone’s core. Most people believe that all animals with horns are male but there are females that have these horns too.
