Reindeer feature is a term used to describe the physical characteristics of reindeer, which are large deer native to northern regions of Europe, Asia, and North America. The two main features of reindeer are antlers and hooves. Antlers are bony structures that grow from the skull of deer and are shed and regrown each year. Hooves are the hard, keratin-covered structures on the feet of ungulates, such as deer, that provide support and protection.
