Horns vs. Antlers

At first glance, horns and antlers may look similar, but they are actually very different structures with unique characteristics. Both are found on members of the hoofed mammal group, yet they differ in how they grow, what they are made of, and which animals possess them.

Horns are found on animals such as antelope, goats, sheep, and cattle. A horn consists of a permanent bony core covered by a sheath made of keratin, the same material found in human hair and fingernails. Horns grow continuously throughout an animal’s life and are not shed. In most species, both males and females may have horns, although they are often larger in males.

Antlers, on the other hand, are found primarily on members of the deer family. Unlike horns, antlers are made entirely of bone and are shed and regrown each year. During growth, antlers are covered in a soft, blood-rich skin called velvet, which supplies nutrients to the developing bone. Once fully grown, the velvet is shed, leaving behind the hard antlers used for display and competition.

Animals use horns and antlers for a variety of purposes, including defense, establishing dominance, attracting mates, and competing with rivals. While horns provide a permanent tool throughout the year, antlers represent one of the fastest-growing bone structures in the animal kingdom and are regrown annually.

Although they may appear similar, horns and antlers are remarkable adaptations that reflect the diverse ways animals have evolved to survive and thrive in their environments. Explore the species in our collection to discover these fascinating natural structures up close.
