Gnawtlers elk antlers11/4/2023 In most cases, the bone at the base is destroyed by osteoclasts and the antlers fall off at some point. This dead bone structure is the mature antler. Once the antler has achieved its full size, the velvet is lost and the antler's bone dies. Growth occurs at the tip, and is initially cartilage, which is later replaced by bone tissue. Antlers are considered one of the most exaggerated cases of male secondary sexual traits in the animal kingdom, and grow faster than any other mammal bone. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone. Velvet covers a growing antler, providing blood flow that supplies oxygen and nutrients.Įach antler grows from an attachment point on the skull called a pedicle. The "horns" of a pronghorn (which is not a cervid but a giraffoid) meet some of the criteria of antlers, but are not considered true antlers because they contain keratin. Nevertheless, fertile does from other species of deer have the capacity to produce antlers on occasion, usually due to increased testosterone levels. Only reindeer (known as caribou in North America) have antlers on the females, and these are normally smaller than those of the males. A horn's interior of bone is covered by an exterior sheath made of keratin (the same material as human fingernails and toenails).Īntlers are usually found only on males. In contrast to antlers, horns-found on pronghorns and bovids, such as sheep, goats, bison and cattle-are two-part structures that usually do not shed. The musk deer, which are not true cervids, also bear tusks in place of antlers. However, one modern species (the water deer) has tusks and no antlers and the muntjacs have small antlers and tusks. In most species, antlers appear to replace tusks. The ancestors of deer had tusks (long upper canine teeth). Structure and development Male fallow deer fighting Two sambar deer fighting, Silvassa, IndiaĪntlers are unique to cervids. Etymology Īntler comes from the Old French antoillier (see present French : "Andouiller", from ant-, meaning before, oeil, meaning eye and -ier, a suffix indicating an action or state of being) possibly from some form of an unattested Latin word *anteocularis, "before the eye" (and applied to the word for "branch" or " horn" ). Antlers are shed and regrown each year and function primarily as objects of sexual attraction and as weapons. They are generally found only on males, with the exception of reindeer/caribou. Antlers are a single structure composed of bone, cartilage, fibrous tissue, skin, nerves, and blood vessels.

The park’s official website also cautions against imitating the noises the bulls are making, known as bugling, noting it can cause a hazardous situation for both the person and the animal.
