There are two types of camels, dromedary with one hump and Bactrian with two humps. Dromedary camels are tall and can walk, run, transport goods and carry people in the desert. Bactrian camels have stubby limbs and are better suited for walking on gravel and snow.
Bactrian camels living in the Gobi Desert are very different from Arabian camels or dromedaries that have a hump. The former is adapted to the cold desert, the latter to the heat desert. But both are descendants of the same ancestor, primitive camels.
Primitive camels lived 12 million years ago and looked like both horses and camels today. Months without water Dromedaries can survive for months without water as long as they can eat enough plants. It doesn't urinate much and only sweats when its body temperature exceeds 40, which can greatly save water.
During periods of drought, dromedaries can last for up to a week without food or water. At this point, it consumes the nutrients in the hump. From the 5th century BC onwards, the inhabitants of the Middle East, Egypt and the Sahara region used dromedaries instead of horses to transport goods and travel.
Camels have become veritable "ships of the desert".
Bactrian camels have two humps and are animals adapted to cold climates. Whereas, dromedaries have only one hump and are more suitable for desert life. The mixed-breed of both is larger than both camels, has a hump, and is good at carrying animals.
Female hybrids can mate with male Bactrian camels and give birth to young. Such mixed camels can be seen in Kazakhstan. The human-caused hybridization of camels and large alpacas became kama, and scientists wanted to find out how similar the two species were through experiments.
Dromedary camels weigh six times as much as large alpacas, so female vicuñas need to be impregnated through artificial insemination. Female dromedary was conceived without success. Half-breeds are even smaller than large alpacas, have camel-like short ears and long tails, no humps, and have large alpaca-like split toes instead of camels' large paws.
Kama became sexually mature after the age of 4 and became interested in female alpacas and alpacas. Later, another female Kama was born through artificial insemination. Because both camels and large alpacas have 74 chromosomes, scientists hope that the female Kama will be able to give birth.
If successful, it means that it is possible to increase the size of the South American camel, the production of meat, the production of wool, and the ability to carry caterment. The Kama appears to have inherited the temperament of its parents and shows a link between the species of the camelidae family in the Old and New Worlds. Agree with 1|Comments.

Single, temperate desert. Double, tropical desert.

The differences between dromedary and bactrian are:
1. The distribution is different.
Bactrian camels are produced in China and Mongolia in Asia, and China is mainly in Xinjiang, Inner Mongolia, Qinghai, Gansu and other places.
Dromedary camels are mainly found in northern Africa, western Asia, some from the Republic of Sudan, Ethiopia, Somalia and other places, and have been domesticated in central or southern Arabia thousands of years ago, and are now mostly distributed in West India to Pakistan, and then to Iran to North Africa.
2. Different body types.
The Bactrian camel is sturdy and muscular, and when it is full, the Bactrian is plump and erect, and when it is extremely dehydrated, it can break down the fat in the hump to produce water and heat. Drink up to 57 litres of water at a time in order to restore the normal water content in the body. They eat almost all plants that grow in desert and semi-arid areas, such as Saxon, Populus euphratica, S. canopus, etc.
The dromedary camel has the same appearance as the Bactrian camel, with thicker eyelashes and small, hairy ears. Among them, the male dromedary has a soft upper jaw and can give birth to a pink "bag" to attract the opposite sex during mating season.
3. The functions are different.
Bactrian camels are more suitable for heavy loads. Bactrian camels can carry 170-270 kg for 4 consecutive days, walk about 47 kilometers a day, and reach a maximum speed of about 16 kilometers per hour. At the same time, its ears are covered with dense hair, which can resist the attack of wind and sand.
In addition, the warm inner fleece and coarse outer fur of the Bactrian camel can be collected and separated for processing, producing about 7 kg of wool fibres per year, which can be used for spinning or knitwear.
Dromedary camels are more suitable for riding. Dromedaries are taller than Bactrian camels, run faster, and can maintain speeds of 13-14 km/h if manned. In addition, dromedaries can also be used to carry cargo, and their milk and meat are available for human consumption.

Camels are not only Bactrian camels, but also dromedary camels.
There are not only Bactrian camels, but also dromedary camels, of which Bactrian camels are generally used to carry people, and dromedaries are generally used to carry goods.
Dromedary: Smaller, weighing around 450 kg, with bushy eyelashes, small and hairy ears, sexually mature males at 5-6 years of age and females at 3-4 years of age.
Bactrian camel: easy to ride, suitable for load, weighing about 650 kg, with long hair, it can feed on desert plants such as poplar, xanthoxylon tree, and sand canopy.
The role of the camel's hump:
1. The hump of the camel can store fat, and when they are on a long journey, they can convert the fat into energy and water by decomposing it, so as to ensure their own life safety.
2. The fat in the hump will produce metabolic water after being oxidized, 1 gram of fat can produce gram metabolic water, and a 45 kg hump can produce 50 kg of metabolic water.
3. The hump is not a water bag, but a huge energy storage bank, which can provide the camel with material security for energy consumption.

It is wrong that there is only one type of camel, the Bactrian camel.
Camels are divided into Bactrian camels and dromedary camels, Bactrian camels are distributed in the hail area of Xinjiang in Australia and China, and dromedary camels are distributed in India and Sudan.
and Somalia.
area, and the camel body is relatively tall, the limbs are long, the hooves have two toes and have a thick skin, suitable for walking in the sand, in addition, the hump distance of the Bactrian camel is about 50 cm.
Features of the hump
Camels can survive without water for 2 weeks and up to a month without food. The hump stores fat, which can be broken down into nutrients for the camel to survive when food is not available.
In addition, the camel's stomach contains many small bubbles in the shape of bottles, which are used to store water. Camels can be used for riding, carrying and carrying, pulling carts, plowing fields, etc., and are indispensable partners for the people and geological exploration and archaeological workers in the desert and Gobi region.

The dromedary in the tropical desert and the Bactrian in the temperate desert are different because of the different environments in which they live, so the body structure is different Here's a specific introduction to dromedaries and Bactrian camels Dromedary and Bactrian camels One or two humps The Bactrian camel that lives in the Gobi Desert is very different from the Arabian camel or dromedary that has a hump. The former is adapted to the cold desert, the latter to the heat desert.

It is right that camels are divided into two types, double hump and single hump. The one with 1 hump, called dromedary, is the most prevalent camel in the world, accounting for about 94% of the world's camel population, and is native to the Middle East and the Horn of Africa. The one with 2 acres of camel concessions, called Bactrian camels, occurs less frequently, accounting for about 4% of the world's camel population, and is native to parts of Central Asia.

1. Nose. Because they have a lot of extremely thin and tortuous pipes in their noses, the pipes are usually moistened with liquid, and when the body is short of water, the pipes immediately stop secreting fluid, and form a layer of crust on the surface of the pipes, which is used to absorb the exhaled water without losing it from the body; When inhaled, the water in the crust is sent back to the body. In this way, water is repeatedly circulated and used in the body, so it can withstand thirst. >>>More
