What is a stag with twelve-point antlers known as?

A stag with twelve-point antlers is known as a royal stag. The name comes from traditional British deer terminology, in which a red deer male’s status is described by the number of points on its antlers.

In this system, a stag with fewer than ten points may be called a brocket or staggard depending on age and antler development, while a stag with ten points is commonly a great stag. A twelve-point stag is a royal, and one with fourteen points is often called an imperial. The terms refer to antler points rather than the animal’s age alone, although older and healthier stags are more likely to develop larger antlers.

Red deer antlers are made of rapidly growing bone. They begin developing beneath a covering called velvet, which supplies blood to the growing tissue. Once the antlers harden, the stag rubs away the velvet against trees and vegetation. Antlers are then used in displays and fights during the autumn rut, when males compete for access to females.

Different countries and hunting traditions use slightly different naming systems, but “royal stag” is the traditional British term for a twelve-point red deer stag.
