Long-horned describes animals that have exceptionally long horns growing from their heads. Texas longhorn cattle are probably the most famous example: their horns can span up to seven feet from tip to tip, wider than most people are tall. These impressive horns developed over centuries as cattle adapted to life on the open range, where longer horns helped them defend against predators like wolves and mountain lions.

You'll also encounter long-horned beetles, a family of insects named for their extraordinarily long antennae that can stretch several times longer than their bodies. Some species have antennae so lengthy they look almost comical, like a beetle wearing a pair of absurdly oversized party streamers.

Whether describing cattle, beetles, or other creatures, long-horned tells you that the animal's most notable feature is those extended horns or horn-like structures. When you see a long-horned animal, those impressive horns are usually the first thing that catches your eye.
