A horn is a pointed projection of the skin on the head of various mammals, consisting of a covering of horn (keratin and other proteins) surrounding a core of living bone. True horns are found only among the ruminant artiodactyls, in the families Antilocapridae and Bovidae. These animals have one or occasionally two pairs of horns, which usually have a curved or spiral shape, often with ridges or fluting. In many species only the males have horns. Horns start to grow soon after birth, and continue to grow throughout the life of the animal (except in pronghorns, which shed the outer layer annually, but retain the bony core).
One creature with the weirdest horn in the world is a bull named Lurch. According to the Guinness Book of Records, he is the bull with the largest horn circumference in the world, measuring 37.5 inches.

Not only mammals have horns, some insects also do. The Atlas beetle, Chalcosoma atlas, is a species of beetle with horns. They are found in southern Asia, especially Malaysia, remarkable for their size (25-130 mm). As common in many insect species, the male is larger than the female and usually two males will fight for a female for mating.
Another insect with a distinct horn-like object is the Lucanus cervus, the best-known species of stag beetle and is sometimes referred to simply as the stag beetle. Once quite common, the population of the Lucanus cervus, along with that of other species of beetles which feed on wood, is in steep decline, and is now listed as a globally threatened/declining species.
