Deer are a popular game animal in North America and many hunters pursue them each year. But why do deer have antlers?
The answer lies in evolution and survival. Antlers are a means for male deer to assert their dominance over other males and to attract mates. The size of a male’s antlers is a good indication of his health and strength both of which are important traits to female deer.
In the wild deer face many predators including coyotes wolves and bears. Their main defense against these predators is their speed and agility. But in some situations antlers can also be used as weapons. For example a buck with large antlers can fend off a coyote or wolf by swinging his head and using the sharp points of his antlers to stab the predator.
Deer are not the only animals that use antlers for defense. Moose caribou and elk are just a few of the other species that sport antlers. But of all the animals with antlers deer have the largest and most complex antlers.
The antlers of a deer are made up of two parts: the pedicle and the antler beam. The pedicle is a small bony protrusion that extends from the deer’s skull. The antler beam is the main antler shaft that grows from the pedicle.
Deer antlers are the fastest growing tissue in the animal kingdom and can grow up to an inch per day. Antlers are covered in a layer of velvet during their growth phase. This velvet is supplied with blood vessels that help the antlers grow. Once the antlers are fully grown the velvet is shed and the hard bony antlers are revealed.
The size and shape of a deer’s antlers can vary depending on the species. Mule deer for example tend to have large wide antlers while white-tailed deer have smaller more compact antlers.
No two sets of deer antlers are alike and each set is unique to the individual deer. Much like human fingerprints the pattern of ridges and valleys on a deer’s antlers can be used to identify individual animals.
Deer antlers are shed each year and grow back bigger and stronger the following year. This process is known as antler casting and usually occurs in late winter or early spring.
As a deer gets older its antlers will become larger and more complex. This is due to the accumulation of testosterone and other hormones in the deer’s body. Antler size is also influenced by the quality of the deer’s diet. A healthy diet rich in minerals and other nutrients is essential for antler growth.
So there you have it! That’s why deer have antlers. Now you can impress your friends and family with your knowledge of deer anatomy the next time you go hunting!
