Rump (animal) in the context of "Coccyx"

Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, as dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head and body, and weighed only 113 grams (4.0 oz). The heaviest dog was an English Mastiff named Zorba, which weighed 314 pounds (142 kg). The tallest known adult dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.

The springbok or springbuck (Antidorcas marsupialis) is an antelope found mainly in south and southwest Africa. The sole living member of the genus Antidorcas, this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies are identified. A slender, long-legged antelope, the springbok reaches 71 to 86 cm (28 to 34 in) at the shoulder and weighs between 27 and 42 kg (60 and 93 lb). Both sexes have a pair of black, 35-to-50 cm (14-to-20 in) long horns that curve backwards. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light brown coat marked by a reddish-brown stripe that runs from the upper foreleg to the buttocks across the flanks like the Thomson's gazelle, and a white rump flap.

Active mainly at dawn and dusk, springbok form harems (mixed-sex herds). In earlier times, springbok of the Kalahari Desert and Karoo migrated in large numbers across the countryside, a practice known as trekbokking. A feature, peculiar but not unique, to the springbok is pronking, in which the springbok performs multiple leaps into the air, up to 2 m (6.6 ft) above the ground, in a stiff-legged posture, with the back bowed and the white flap lifted. Primarily a browser, the springbok feeds on shrubs and succulents; this antelope can live without drinking water for years, meeting its requirements through eating succulent vegetation. Breeding takes place year-round, and peaks in the rainy season, when forage is most abundant. A single calf is born after a five- to six-month-long pregnancy; weaning occurs at nearly six months of age, and the calf leaves its mother a few months later.

The tail of the horse and other equines consists of two parts, the dock and the skirt. The dock consists of the muscles and skin covering the coccygeal vertebrae. The term "skirt" refers to the long hairs that fall below the dock. On a horse, long, thick tail hairs begin to grow at the base of the tail, and grow along the top and sides of the dock. In donkeys and other members of Equus asinus, as well as some mules, the zebra and the wild Przewalski's horse, the dock has short hair at the top of the dock, with longer, coarser skirt hairs beginning to grow only toward the bottom of the dock. Hair does not grow at all on the underside of the dock.

The tail is used by the horse and other equidae to keep away biting insects, and the position and movement of the tail may provide clues to the animal's physical or emotional state. Tail carriage may also be a breed trait. Tails of horses are often groomed in a number of ways to make them more stylish for show or practical for work. However, some techniques for managing the tails of horses are also controversial and may constitute animal cruelty.

The oribi (/ˈɔːrəbi/; Ourebia ourebi) is a small antelope found in eastern, southern and western Africa. The sole member of its genus, it was described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1783. While this is the only member in the genus Ourebia, eight subspecies are identified. The oribi reaches nearly 50–67 centimetres (20–26 in) at the shoulder and weighs 12–22 kilograms (26–49 lb). It possesses a slightly raised back, and long neck and limbs. The glossy, yellowish to rufous brown coat contrasts with the white chin, throat, underparts and rump. Only males possess horns; the thin, straight horns, 8–18 centimetres (3.1–7.1 in) long, are smooth at the tips and ringed at the base.

Typically diurnal, the oribi is active mainly during the day. Small herds of up to four members are common; males defend their group's territory, 25–100 hectares (62–247 acres) large. It is primarily a grazer, and prefers fresh grasses but also browses occasionally. A seasonal breeder, the time when mating occurs varies geographically. Unlike all other small antelopes, oribi can exhibit three types of mating systems, depending on the habitat – polyandry, polygyny and polygynandry. Gestation lasts for six to seven months, following which a single calf is born; births peak from November to December in southern Africa. Weaning takes place at four to five months.
