CAMEL FACT SHEE T KINGDOM: Animalia PHYLUM: Chordata CLASS: Mammalia ORDER: Artiodactyla FAMILY: Camelidae GENUS: Camelus (Linnaeus, 1758) SPECIES: Camelus bactrianus, Camelus dromedarius A camel is either of the two species of large even - toed ungulate in the genus Camelus, the Dromedary (single hump) and the Bactrian Camel (double hump). Both are native to the dry and desert areas of Asia and northern Africa. The average life expectancy of a camel is 30 to 50 years. Humans first domesticated camels approximately 5,000 years ago. DISTRIBUTION AND NUMBERS: Although there are almost 13 million Dromedaries alive today, the species is extinct in the wild . There is, however, a substantial feral population estimated at 700,000 in central parts of Australia, descended from individuals that escaped from captivity in the late 19th century. This population is growing at approximately 11% per year and in recent times the state government of South Aust ralia has decided to cull the animals using aerial marksmen, claiming the camels use too much of the limited resources needed by sheep farmers. The Bactrian Camel once had an enormous range, but is now reduced to an estimated 1.4 million animals, mostly domesticated. It is thought that there are about 1000 wild Bactrian Camels in the Gobi Desert, and small numbers in Iran, Afghanistan, Turkey and Russia. A small population of introduced camels, Dromedaries and Bactrians, survived in the Southwes t United States until the 1900s . These animals, imported from Turkey, were part of th e US Camel Corps experiment, used as draft animals in mines, and escaped or were released after the project fell through. CAMEL HYBRIDS: Bactrian camel have two humps and are rugged cold - climate camels , while Dromedaries have one hump and are desert dwellers. Drom edary hybrids are called Bukhts . The females can be mated back to a Bactrian to produce ¾ - bred riding camels. These hybrids are found in Kazakhstan. The Cama is a camel/llama hybrid bred by scientists who wanted to see how closely related the parent species were. The Dromedary Camel is six times the we ight of a Llama . Though born even smaller than a Llama calf, the Cama had the short ears and long tai l of a camel, no hump and Llama - like cloven hooves rather than the Dromedary - like pads. At four years old, the Cama became sexually mature and interested in Llama and Guanaco females. A second Cama (female) has since been produced using ar tificial insemina tion. The Cama apparently inherited the poor temperament of both parents as well as demonstrating the relatedness of the New World and Old World camelids. ADAPTATIONS TO DESERT ENVIRONMEN T: Camels are well known for their humps. They do not, however, lit erally store water in them as is commonly believed, though they do serve this purpose through roundabout means. Their humps are a reservoir of fatty tissue, while water is stored in their blood. However, when this tissue is metabolized, it is not only a so urce of energy, but yields through reaction with oxygen from the air 1111 g of water per 1000 g of fat. This allows them to survive without water for about two weeks, and without food for up to a month. Their red blood cells have an oval shape, unlike th ose of other mammals, which are circular. This is to facilitate their flow in a dehydrated state. These cells are also more stable, in order to withstand high osmo tic variation without rupturing when drinking large amounts of water. Camels are able to wi thstand changes in body temperature and water content that would kill most other animals. T heir temperature ranges from 93 degrees F at night, up to 106 degrees F at day; only above this threshold they start to sweat. This allows them to preserve about fiv e liters of water a day. However, they can withstand at least 25% weight loss due to sweating. The thick coat reflects sunlight. A shaved camel has to sweat 50% more to avoid overheating. It also insulates them from the intense heat that radiates from ho t desert sand. Their long legs also help with this by keeping them further away from the sand. Their mouth is very sturdy, to be able to eat thorny desert plants. Long eyelashes and ear hairs, together with sealable nostrils , prevent sand from entering. Their pace (always moving both legs of one side at the same time) and their widened feet help them move without sinking in. CAPTIVITY: Camels used for entertainment are often subjected to abuse . Even under the best of circumstances, captivity can be hell for animals meant to roam free. Kept in small, barren cages, forced to sleep on concrete slabs, and imprisoned behind iron bars, performing animals often suffer from malnutrition, loneliness, th e denial of all normal pleasures and behaviors, loss of freedom and independence, even lack of veterinary care, and filthy quarters. Attracting customers is the first consideration and the animals' welfare is often the last. Even when the mere display of t he animals themselves is the "draw," the animals rarely receive proper care -- and almost never the socialization and stimulation they crave. Animals used for entertainment are subjected to rigorous and abusive training methods to force them to perform st ressful, confusing, uncomfortable, and even painful acts; training methods can include beatings, the use of electric prods, food deprivation, drugging, and surgically removing or impairing teeth and claws. Confined to tiny cages and gawked at by crowds, an imals in exhibits and acts endure constant stress. They may suffer from temperature extremes and irregular feeding and watering. Without exercise, they become listless, their immune systems are weakened, and they become prone to sickness; many resort to se lf - mutilation in reaction to stress or boredom. Mental illness is rampant among confined animals. Torn from their families and deprived of all dignity, every part of their lives is controlled by their capt ors. While zoos and aquariums may appear to be educational and conservation - oriented, most are designed with the needs and desires of the visitors in mind, not the needs of the animals. Many animals in zoos and aquariums exhibit abnormal behavior as a result of being deprived of their natural environme nts and social structures. Some zoos and aquariums do rescue some animals and work to save endangered species, but most animals in zoos were either captured from the wild or bred in captivity for the purpose of public display, not species protection. The v ast majority of captive - bred animals will never be returned to the wild. When the facility breeds too many animals they become "surplus" and often are sold to laboratories, traveling shows, shooting ranches, or to private individuals who may be unqualified to care for them.
