This photo is from one of our trips to Yellowstone, a marvelous place with incredible wildlife. What is the difference between antlers and horns?
Answer:
Antlers are made of bone. When the antler matures, the bone dies. They are shed and regrown every year. Horns have a bone core, covered with a sheath of keratin and other proteins. The bone core of a horn remains alive throughout the animal's life.
