The term camel, (from the Arabic جمل, derived from the triconsonantal root signifying "beauty"), is also used more broadly to describe any of the six camel-like creatures in the family Camelidae: the two true camels, and the four South American camelids, the llama, alpaca, guanaco, and vicuña.
The average life expectancy of a camel is 40 to 50 years. A fully grown alt camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump. The hump rises about 30 inches (76.20 cm) out of its body. Camels can run at up to 65 km/h (40 mph) in short bursts and sustain speeds of up to 40 km/h (25 mph).
Fossil evidence indicates that the ancestors of modern camels evolved in North America ring the Palaeogene period (see also Camelops), and later spread to most parts of Asia. Humans first domesticated camels well before 2000 BC.[1][2]
骆驼是骆驼科骆驼属的动物，只有两种，鼻孔能开闭，足有肉垫厚皮，适合在沙漠中行走，背有肉峰，内蓄脂肪，胃有三室，第一胃室有20-30个水脬，可以贮水，红血球可以大幅膨胀吸水来贮水，所以耐饥渴，可以多日不吃不喝，一旦遇到水草，可以大量饮水贮存。所以被称为“沙漠之舟”。生活在沙漠边缘的人类早在公元前3000年已经开始驯养骆驼，作为役畜，以供驮运和骑乘，有许多国家有倚赖骆驼为生的骆驼牧民，甚至有骆驼骑兵。
单峰骆驼毛短，主要生活在北非洲和西亚洲、印度等热带地域，生活在沙漠地带的牧民以骆驼奶甚至骆驼血作为食物，目前全世界只有1400万头，全部是家畜。19世纪末澳大利亚曾从非洲引进部分单峰骆驼，后来由于不再应用役畜，只向中东出口，大约有3200头散落到澳大利亚沙漠重新野化。

Camel hair is generally brown, some yellow, gray and other colors; Health atop a cluster hair, fluffy hair long; Hump mast and fullness, even after the summer shed a thick resial hair; more sturdy limbs, and the wide-toed. A Bactrian camel and two single peak. Bactrian camel in northern China have extensive domestication, and so far in the northwest region of Inner Mongolia is still to see. Last very long once extraoral trade between Beijing and the major means of transport, known as the "boat of the capital" reputation. Unimodal camel that has been distributed in China's Xinjiang area, but now only found in the Arabian Peninsula, India and Northern Africa, and other places. Its hair was shorter, with a life span of 50 years.
Camel rid of a water balloon, can store a lot of water; Camel's Hump two tall, which can store more than 100 kg of fat, if necessary, could be transformed into a water and energy and to maintain the camel's life activities. Therefore, in the desert, can be 34 consecutive days at home, suitable for long distance. Andrew camel in the desert will become the major means of transport. As camels walking or jogging at the time, while extending the left or right of way, So who will ride sitting very unstable.
Camel is a desert area of transport. The world has a single peak and the Bactrian camel, the most obvious difference is the number of different hump. I made in Bactrian camel, a spine around the same two saddle Hump. We usually see the camels are home, their ancestors were wild camels living in Xinjiang, Gansu, Qinghai, Inner Mongolia desert region, with its home is the difference between camel : Hump short, slender legs, a body of short hair, pale yellow color. As the number of wild camels extremely rare, has been listed as a protected species.
In the desert long-distance running, often hungry and thirsty, and then the fatty hump will be biodegradable, Camel intimate supply needed nutrients and moisture. Camel in the desert dry run thirst, because it usually drink less, one can drink within 10 minutes more than 100 liters of water to drink; Meanwhile drainage less in the summer day from only about one or urine. it is not easy openings to prevent water on the body, in the summer desert, It can be eight days without water will not dry out.
Camel good at taking the desert, because it had two unusual soles of the feet, to hold next life as generous as the spring winds. walking on toes to the front stretched apart, then walk in the sand surface subsidence that will Shawodi somewhere. In its travel, lift up his head high, eyes will be on the ground sunlight reflected by the high fever burns. Camel long eyelashes eyes, automatically opening and closing of the nose, covered with hair closely ears, it can attack from the sand ...
As early as 2000 years ago, the Western Han Dynasty, the Chinese people will use camels as leading to the Western Regions of transport.
2.Camel English name: Camel, llama The camel has two kinds, a some camelback peak camel and twocamelbacks bactrian camel. A peak camel quite is big, can walk in thedesert can run, may transport freight, also can carry on the back theperson. The bactrian camel four limbs are stubby, suits in the graveland the snowy area walks. The camel and other animals are dissimilar,specially bears the hunger to bear thirstily. The people only can ridethe camel to cross the desert, therefore the camel has "boat of thedesert" laudatory name.

The camel cancontinuously 45 days not eat food, is depends on in the camelback thefat.

These "the equipment" cause the camel not to fear thesandstorm. Sand soft, the person foot steps on is very easy to fallinto, but camel's sole is flat, under the foot has the thick soft meatcushion, such sole causes the camel to walk on the sand freely, cannotfall into in the sand. The camel is the double hoof item camel branch camel is two kind oflarge-scale counter- hay mammal the general designation, divides apeak camel and two peaks camels.

After training and managementappropriate camel personality tame, but is also easy to get angry,especially in oestrus period. Gets angry when the mouth spurts thesaliva, and can nip the person, kick the person, is extremelydangerous. The camel originally proces to North America,approximately in 40 billion years ago about. Afterwards itsdistribution scope expanded to South America and Asia, but vanished inits habitat. In the tradition the camel serves as importantly carrieson the back the domestic animal. Although two peaks camels approachingspeed only is each hour 3 to 5 kilometers, but can the long timeshoulder the heavy item, every day feasible 50 kilometers. Peak camelleg longer, the person rides sits when can maintain each hour to reachfor 18 hours 13 to 16 kilometers speeds.

In thecamelback fat not only serves as the nutrition to originate, the fatoxidation may proce the moisture content. Therefore the camel cannot eat does not drink on severalth, according to the record, thecamel once 17 days potable waters still did not survive gets down.
