When people say, "That whitetail has some nice horns" or something like that. THEY ARE ANTLERS PEOPLE.

Antlers vs. Horns

Members of the deer family (which includes caribou, deer, elk, and moose) have antlers. Antlers are solid bone and shed annually. They are one of the fastest growing natural materials in the world. Horns are found on bison, sheep, and goats. Unlike antlers, horns are hollow, never shed, and grow continuously. If broken, they do not grow back. They consist of a keratin sheath surrounding a core of bone. Females have horns with half-moon curves, while males have larger horns that curve around each side of the head.
