In most cases, the bone at the base is destroyed by osteoclasts and the antlers fall off at some point. [6] 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 ...
Male antlers grow more branching points and measure anywhere between 39 inches and 53 inches in beam length, whereas female antlers only measure about 20 inches and generally have a simpler structure.
Unlike other deer species, female reindeer grow antlers. Male antlers can grow to lengths of fifty-one inches, while female antlers are smaller, at twenty inches. So, where do reindeer live?
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.
The antlers are testosterone-driven and as the stag's testosterone levels drop in the autumn, the velvet is shed and the antlers stop growing. [11] With the approach of autumn, the antlers begin to calcify and the stags' testosterone production builds for the approaching rut (mating season).
Males grow longer and thicker antlers which they use for fighting. Their antlers can grow to be as large as 51 inches long , whereas a female's antlers only grow to around 20 inches long.
Rubs continue to appear throughout the autumn season, especially during the mating season (called the rut), until the male deer shed their antlers in winter. [1] The area between the forehead and antlers contains a large number of apocrine sweat glands , and leave a scent that communicates a challenge to other male deer while also attracting ...
