Cowboy Dictionary - Letter A
Antlers - Antlers are bony protrusions found on the skulls of animals in the family Cervidae. Commonly called the "deer family," Cervidae include animals such as deer, elk, moose, and reindeer. With one exception antlers are grown only by the males of the species. In reindeer both males and females grow antlers. Antlers are not a permanent part of the animals' skull but instead are grown, shed, and re-grown annually.
