Why are camels called ships of the desert ?

In the desert, camels can usually be seen carrying heavy items in the desert, and camels are known as the "ship of the desert" and are an indispensable means of transportation in desert areas. For this, we will start with the physiological characteristics of camels. First of all, camels have a special body structure and are very adapted to life in the desert.

The camel has a tall body, slender limbs that can advance in great strides, hooves as large as plates, and spring-like pads on the toes to avoid falling into the sand; The eyelids are double-layered, and the eyelashes are very long, which can block sand and dust and prevent blindness; The nostrils are obliquely open, which can be opened and closed freely to prevent dust from entering, and the olfactory cells are relatively concentrated, not only can they look for food, but they can smell the feeling of humidity in the arid desert and the tasteless water source, and from a long distance.

In addition to its ability to walk in the desert and find the source of life, the camel's hump allows it to go further in the desert. There are two types of camels, dromedaries 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. The camel's hump stores fat, which can be broken down into nutrients for the camel to survive when the camel is not fed. Camels are able to go 4 to 5 days without food, that is, by the fat in the hump.

In addition, the fat in the hump can also help it regulate its body temperature, keeping it warm in winter and heat in summer. In addition to the hump, the camel's stomach contains many small bottle-shaped bubbles, which are where the camel stores water, and the water in these "bottles" allows the camel to not be life-threatening even if it does not drink water for several days. <>

Camels have a special physiological function to prevent water loss in drought conditions. Camels generally do not sweat, the water in their blood is well maintained, and they are not easily dehydrated. The camel's massive snout is a key part of the water conserved.

The inner layer of the nose is swirled in shape, increasing the area through which exhaled air can pass. During the night, the inner layer of the nose ** moisture from the exhaled air while cooling the gas. It has been calculated that these special abilities of the camel allow it to save 70% more water than the warm gas exhaled by humans.

If a camel carries a 200-kilogram load and travels 40 kilometers a day, it can walk in the desert for 3 days in a row. When not loaded, it can run up to 15 kilometers per hour for 8 hours straight. Therefore, the camel is bestowed with the reputation of "Ship of the Desert", and it is well deserved.

Because camels are extremely hungry and thirsty, they are called the ships of the desert.

Camels, known as the "ships of the desert", have a small head and a thick, long, curved neck like a goose's neck. The body is tall and has brown body hair. Extremely able to endure hunger and thirst. 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.

Habits:

Camels are very hungry and thirsty, and can go days without drinking water every time they drink enough water, and can still move in hot, arid desert areas. Due to the fact that they have a lot of extremely thin and tortuous tubes in their noses, the tubes are usually moistened with liquid.

When there is a shortage of water in the body, the tube immediately stops secreting fluid, and forms a crust on the surface of the pipe, 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.

The camel is"Ship of the Desert", because of:

Camels are hungry and thirsty, docile, not afraid of wind and sand, and good at walking the desert, and are recognized by the world as the ship of the desert and an indispensable means of transportation in desert areas. There are two types of camels: unimodal and bimodal. The camel produced in China is a Bactrian camel, with a height of 2 meters, weighing about 450 kilograms, and a lifespan of 35-40 years.

Camel was originally wild, domesticated more than 4,000 years ago, now wild camel is almost extinct in the world, only in the western part of China's Inner Mongolia, Xinjiang Gobi and northern Gansu can still be found in sparsely populated places, is listed as a national first-class protected animal. The greatest skill of the camel is to trek non-stop in the desert, and can go without drinking water for ten days and a half months. This is because camels have a special physiological function to prevent water loss in drought situations.

The camel's massive snout is a key part of the water conserved. The inner layer of the camel's nose is swirled, increasing the area through which exhaled air can pass.

The desert environment is harsh and dry, with a large temperature difference between day and night, and water plants are scarce. Camels have lived in the desert for a long time and have a range of adaptability in their bodily functions. Its eyes have two rows of long, thick eyelashes, dense ear hairs in the ear shell, and wind protection valves in the nostrils to block the invasion of wind and sand.

The soles of its feet have about centimeters thick pads, which can withstand the high temperature of 70-80 in the desert or the severe cold of winter, and the camel is covered with brown fluff about 10 cm long, which can be used to resist cold in winter, and form a cooling gap between the fluff and ** in summer, which can prevent high temperature radiant heat.

Camels have amazing endurance and can go 20 days without drinking water when the temperature is 50 and the water loss reaches 30 of their body weight; It can also carry up to 200 kilograms and travel at a speed of 75 kilometers a day for four days. The camel bee is used to store fat, and at most it can hold 50 kg of fat, which is about 1 5 of body weight. The stomach and muscles of the camel can store a certain amount of water.
