While growing, antlers are covered with a soft brown-haired skin called "velvet." Right under this skin are many tiny blood vessels that carry food and minerals to the growing antlers. If an antler is knocked against a tree during the velvet stage, it will bleed. Within four to five months, the antlers are full-sized.
Horns are composed of a bony core covered with a sheath of keratin.
Males of almost all deer species grow antlers, used to battle for females. But reindeer are the only species in which the females also grow antlers, and an explanation can be found by looking at bovids, a closely related family including antelopes, goats and sheep.
Antlers shed annually, but horns stay attached and keep growing. All deer species shed their antlers in winter, after a sustained drop in testosterone ends their life cycle. Several months later, the animals regrow their antlers from spring through late summer.
True horns—simple unbranched structures that are never shed—are found in cattle, sheep, goats, and antelopes. They consist of a core of bone surrounded by a layer of horn (keratin) that is in turn covered by keratinized epidermis. Horn lengths and configurations in various antelopes. The antlers of deer are not horns.
Deer antlers can vary in weight from 3 to 9 pounds. Healthier deer will have heavier antlers because the bone is dense from good mineralization. A bull elk in his prime could have an antler spread of four feet, with each antler weighing 20 pounds. Moose antlers spreading six feet weigh about 40 pounds each.
Antlers are extensions of an animal's skull found in members of the deer family. Antlers are shed and regrown each year and function primarily as objects of sexual attraction and as weapons in fights between males for control of harems.
Unlike human bones, formed antlers have no nerve cells, so they stop signaling pain. At that point, they work as weapons and accessories, and the deer use them to fight, hunt, and woo.
Squirrels, mice, porcupines, even foxes and bears eat antlers, which are full of calcium, phosphorus, and mineral salts. By summer, wild animals large and small will have nearly devoured every antler in the forest.
Unlike horns, which are permanent structures, antlers are shed and re-grown each year. Some deer begin growing their new antlers almost immediately after the old ones have been shed, while others may exhibit a delay between shedding and re-growth.
For my study, I defined spike-on-one-side (SOOS) bucks as any buck having either: 1) a side-to-side difference in gross Boone & Crockett score of greater than 50 percent, or. 2) a side-to-side difference of more than two typical antler points. To determine the primary cause of SOOS antlers, I needed samples.
Deer antlers are edible, and not just as a pill used in eastern medicine or a health supplement. Although you would not just bite into a shed antler or boil it up and put it on a plate, recently antlers have grown in popularity as dog chews. This is now a large part of the shed antler market.
We'll start with antlers. Only deer species (the family Cervidae) grow antlers, and in nearly all species only the males grow antlers. (The exception is that female caribou also grow antlers.) Antlers are a bony structure that males grow every year and then they “shed” them, meaning they fall off.
Both male and female reindeer grow antlers, while in most other deer species, only the males have antlers. A male's antlers can be up to 51 inches long, and a female's antlers can reach 20 inches. Unlike horns, antlers fall off and grow back larger each year.
Deer grow and shed antlers every year, requiring large amounts of nutrients and energy. The size and formation of antlers vary widely among deer in general. Antler growth depends on an individual deer's access to quality nutrition, age and genetics.
While most veterinarians advise staying away from antlers for dogs, if you do choose to give your dog an antler, it is a good idea to supervise him while your dog chews on it (or any chew toy).
With that in mind, here are a few ideas of how to turn them into stylish accents for your home.

Antlers are composed of bone. Horns are composed of keratin (same material as hair and fingernails) on the outer portion and live bone on the inner core. Antlers grow from the tip; horns grow from the base.
Only the human male would be endowed with horns, but they certainly wouldn't be used for head butting. One crash with colliding heads and the thin skull would shatter and the scrawny necks break. The horns would most likely be for display purposes only. Females will definitely mate with the long-horns.
Animals use their horns to defend against predators. If an animal's horn is broken or damaged, it will remain that way forever. It does not grow back. Horns are permanent; they are not shed, but grow with the animal throughout its lifespan.
It's official–the coconut crab has the strongest grip of any animal. Researchers at the Okinawa Churashima Foundation in Japan, found that a coconut crab's pinching power corresponds with its size — and that force was tremendous.
Even though we are unable to determine a moose age by its antlers we are able to learn a considerable amount about the social structure and reproductive status of moose as they age.
Deer grow a new pair of antlers each year from the time they are a year old. Antlers begin as layers of cartilage that slowly mineralize into bone. They are soft and easily damaged until they completely mineralize in late summer. The hardened antlers are composed of calcium, phosphorous and as much as 50 percent water.
Moose are not normally aggressive; however, they can become aggressive when they are harassed by people, dogs, and traffic, or when hungry and tired, especially in winter when they must walk through deep snow. Sometimes people throw snowballs at moose or approach them too closely for safety.
Deer antlers are made up of a honeycomb, bone-like tissue. After their antlers are fully-grown again, a drop in testosterone levels causes weakness at the pedicle. The pedicle becomes so weak the antler growth stops and the antlers simply fall off.
While it's true that moose typically aren't aggressive towards people, if provoked, they can be deadly. Unlike deer (the moose's close cousin), moose aren't usually afraid of humans, so they won't run away just because you're there. Here are our tips for avoiding a moose attack while you enjoy the great outdoors.
Although moose aren't more dangerous than bears in terms of behavior, they pose a greater threat of injuring you simply because of their population size. Despite the incidence rates, moose do not tend toward natural aggression. The largest species of the deer family, Alaskan moose are the biggest in the world.
The horns of most animals have a bony core covered by a thin sheath of keratin, the same substance as hair and nails. Rhino horns are unique, however, because they are composed entirely of keratin. The study also ends speculation that the horn was simply a clump of modified hair.
