Deer regrow larger antlers every year

Male deer, like white-tailed and mule deer, shed their antlers annually, typically in late winter or early spring. Driven by hormonal changes, new antlers begin growing almost immediately, forming from bony nubs on the skull. These impressive structures can grow up to an inch per day, initially covered in a fuzzy velvet that supplies vital nutrients. By fall, the velvet sheds, revealing hardened antlers ready for the mating season.
