For centuries, camels have been hailed as the ultimate desert survivors with the iconic hump that inspires wild imaginations and myths. Most commonly, these humps look like portable water tanks; they are ready to drink in the scorching desert heat. Spoiler alert: they are not. Camels don’t carry water in their humps, but that doesn’t make them any less extraordinary. These “ships of the desert” are built to conquer the harshest environments with astonishing adaptations that would put any survival craft to shame. From their ability to go days without a sip to their secret weapon for enduring brutal sandstorms, camels are true desert legends. So, what exactly is inside those humps? Let’s dive into the fascinating world of camels and bust some myths while we’re at it.
Why do camels have humps?
The camel’s hump is in reality a fat reserve, a vital source of energy in periods of food shortage. In the camel trade, the size of a camel’s hump is often considered an indicator of health – a larger hump means that the camel has received better nutrition and is thus healthier. The hump of a well-fed camel is firm and upright; the one for a poor nutrition hanging or empty.
What makes the hump even more interesting is the nutritional quality of the fat stored inside. Just one tablespoon of camel fat contains three times the amount of oleic acid – a highly beneficial omega-9 fatty acid – found in coconut oil. This makes the fat an incredibly efficient and potent fuel source, ensuring that camels can thrive even in the harshest conditions.
Is water really stored in a camel’s hump?
Contrary to many misconceptions, camels do not store water in their humps. The humps act as reservoirs of adipose tissue that are metabolized into energy and water if supplies become scarce.
Camels have managed to survive in the desert thanks to a variety of physiological adaptations.
Water saving:
Camels produce little urine and it is also very concentrated. In addition, their digestive system produces dry feces, which further reduces evaporation of water.
Thermoregulation:
Camels can withstand extreme variations in body temperature, ranging from 34.5°C to 40.7°C, which reduces the need to sweat and therefore conserves water.
Nasal passages:
Their nasal passages are designed to recondense moisture from the exhaled air, thereby reducing the loss of airway water.
These adaptations allow camels to survive for long periods without direct access to water, making them indispensable herd animals across the Gobi and Sahara deserts. Their amazing ability to conserve water has earned them the nickname “Ships of the Desert”.
Where did the myth “camels store water in their humps” come from?
The myth probably arose because of the camel’s incredible ability to go long periods without drinking, even in the harshest desert conditions. Such remarkable endurance creates an illusion that must exist somewhere in the camel to support them. The large, hump-like protrusion on their back may have helped fuel this belief that these humps somehow functioned as water tanks.
But the truth is completely different and even more fascinating. Camels do not store water in their humps but use them as fat reserves. That fat is metabolized when food and water are scarce, giving camels energy and releasing small amounts of water as a byproduct of fat breakdown. The biological adaptation, combined with their efficient water conservation strategies, allows camels to thrive in arid environments.
The myth may also have been fueled by the camel’s cultural significance as the “ship of the desert”. For hundreds of years, camels have been the lifeline of herd animals in the desert regions, able to survive for days without water as they cross the Gobi, Sahara and Arabian deserts under heavy loads. Their ability to survive and unique physiological adaptations have long fascinated humans and inspired legends and stories explaining how they can survive in such adverse conditions.
In reality, camels’ endurance is the result of a combination of adaptations that enable them to withstand significant body water losses, tolerate extreme temperature fluctuations, and conserve water through concentrated urine and dry feces. The myth of water-filled humps may not be true, but the real story of the camel’s survival mechanisms is even more impressive.
Rare facts about camel hump you’ve probably never heard
Here are four interesting facts about camel hump:
Grease containers, not water tanks:
Contrary to popular belief, camel humps do not store water. The fat reserves can weigh as much as 80 pounds and are an important source of energy during times of food scarcity.
Hump Health Indicator:
The size and firmness of a camel’s hump indicates its general health and well-being. A healthy, well-fed camel has a firm, upright hump, while a drooping or collapsed hump indicates depleted fat stores and possible malnutrition.
Species difference:
A one-humped camel is a dromedary, while the two-humped is called a Bactrian. Both species have humps to store fat in them, which allows these camels to go for long distances without eating.

Adaptive evolution:
Ancestral camel species were found in cold climates and developed humps as storage of fats to ensure survival in extreme climates. These fat reserves gradually played a role in their ability to survive long periods without food and harsh temperatures.
