Deer
Deer is a generic term for the deer family (Cervidae), and forms part of the mammalian river heading/case heading. In addition to animals commonly called deer, deer family includes deer, reindeer, and Buddha. On the Korean Peninsula, four species of Baekdu Mountain Deer (Wapati Deer, Manchu subspecies), Continental Deer (Flower Deer, Japanese Deer), Roe deer, and Elk.
Body
The size of the body varies from small species with a body length of about 30 cm and a shoulder height of about 20 cm to large species with a body length of 3.1 m and a shoulder height of 2.35 m (red deer body 250 cm, shoulder 150 cm, weight 250 kg). The legs are long and thin, and the steps are fast and the stride is wide, so it runs well. The feet consist of two middle toes, covered with a cover. There are also two other degenerated toes that are located above the hoof and are not used at all. The deer has a narrower head and a smaller nose and mouth than a cow. The lips can move easily, so they bite the prey. Deer mostly have the front teeth only on the bottom, and a thick plate with rough skin on the top to replace the front teeth. When tearing leaves or branches, the lower teeth press against this thick plate. The upper and lower molars are sharply split at the end, which is good for chewing food.
The vision is slightly lower, but the auditory and olfactory senses are sensitive to the danger. The ears stand tall and straight, so you can hear the sound coming from any direction, and you can figure out the direction in which it sounds. The deer always faces the windy side when eating or resting, in order to hear and smell the predators carried by the wind. The horns of a male with many branches are one of the great characteristics of deer, and are very different from those of cows. The deer's horns fall off from the base's horn every April to May each year, and a new diagonal emerges there. The diagonal is wrapped in velvety, short-haired skin, and numerous blood vessels are distributed inside. When the horns have developed and keratinization is complete, rub it on a tree or the like to peel off the skin. It seems to be related to the size of the horns and the development of tusks. Elk with magnificent tusks do not have horns, and some species have short horns. However, some species distributed in South America have small horns, but some have poor development of tusks.
Life
Habitats vary in forest, wetland, grassland, and tundra, and eat soft grass, bark, small branches, and young shoots. The food is swallowed without chewing enough. The deer's stomach is made up of four parts, one of which is capable of storing food, so that large amounts of food can be quickly eaten. Then, after moving to a safe place, take the stored food as a ball, chew it again, swallow the food and send it to another room above. The deer avoids predators with its sensitive senses, prior knowledge of its behavior, and quick action. Healthy deer are faster than natural enemies such as bears, tigers, leopards, lynx, Canadian lynx, puma, jaguar, Asian lions, European lions, wolves, and monks. Also, unless surprised, the deer stands still and waits for the predator to pass. The deer seeks food only at dawn and around the twilight around the forest, where its appearance is less visible. Most of them live in groups, feed in the morning and evening, and rest in the daytime with a good view. When danger comes, the white hair of the butt is erected to signal other males to warn them. During the breeding season, the males fight against each other with horns, and the male who wins the battle forms a harem with dozens of females. Depending on the species, a gestation period of 6-9 months gives birth to one or two offspring at a time. Females shelter away from other deer herds to give birth. The fawn hides there until it can walk and follow its mother. The offspring become independent after living with their mother for one year of life. It is mainly distributed in North America, South America, Asia, and Europe.
Use
From ancient times, people caught deer, ate meat, and dressed in fur. However, in the late 1980s, more than 20 species of deer became endangered. This is true of Asian deer, including the Colombian white-tailed deer, the key deer, the swamp deer, and the Korean deer. Therefore, deer hunting was banned in many countries, and no hunting zones were established. However, many areas where deer live are being developed as farmland or homes. Today, destroying deer's natural habitat is a major threat to deer populations. Venison is light and light, and it has been used habitually for food since it does not smell much. Meat tastes the best from autumn to early winter, and is usually eaten with bulgogi, roast beef, and hotpot. The deer's horns, especially the diagonals, are called antlers, and they are used as a tonic in oriental medicine because they help blood and strengthen the heart.
Symbol
The stag's horn that periodically falls and rises again is like a "tree of life." It is a universal symbol for rebirth, longevity, sexual desire, light and sun, etc., reflecting the laws of nature. From Scythian legends, Greek mythology and Roman mythology, stag is a powerful symbol in many cultural myths.
Subcategory
The deer family consists of about 150 species. This list includes Ludt, Schroeder, Rottmann and Kuehn (2004); Hernandez-Fernandez and Vrba (2005); Groves (2006); Randi, Mucci, Claro-Hergueta, Bonnet and Douzery (2001); Pitraa, Fickela, Meijaard, Groves (2004);Ruiz-Garcia, M., Randi, E., Martinez-Aguero, M. and Alvarez D.
