Horned animals are species that possess horns, which are hard, bony structures that grow from their skulls. These horns can serve various purposes, including defense against predators, competition for mates, and social signaling within their groups. Common examples of horned animals include cattle, sheep, and goats. Horns are different from antlers, which are shed and regrown annually, primarily found in deer. Horned animals typically have horns for life, and their size and shape can vary significantly among species. The presence of horns can also indicate the animal's age and health.
