Antlers grow very quickly every year on the bulls. As the antlers grow, they are covered in thick velvet, filled with blood vessels and spongy in texture. The antler velvet of the barren-ground caribou and the boreal woodland caribou is dark chocolate brown. [126] The velvet that covers growing antlers is a highly vascularised skin.
As a result of their fast growth rate, antlers are considered a handicap since there is an immense nutritional demand on deer to re-grow antlers annually, and thus can be honest signals of metabolic efficiency and food gathering capability.

Antlers are considered one of the most exaggerated cases of male secondary sexual traits in the animal kingdom, [63] and grow faster than any other mammal bone.
