Camels Dromedary & Bactrian Camels
There are two types of camels. The dromedary camel has one hump. The Bactrian camel has two humps. The dromedary camel makes up about 95% of the world’s camel population. The Bactrian camel makes up about 5% of the camels in the world.
A feral camel is a wild camel that is a descendent of a domesticated camel. They are found in Australia and USA.
Camel Description What Does a Camel Look Like?
Dromedary Camels (One Hump camel)
Dromedary camels, also know as Arabian camels, are the tallest of all camel species. They predominately brown in colour but can range from black to almost white. Their fur (referred to as ‘camel hair’) is short, except for longer, thicker concentrations on the throat, shoulders, and hump. They can be easily identified by their single hump. Adult male Dromedary camels are about 1.8 to 2 m tall at the shoulder and weigh approximately 400 to 600 kg. Females are about 1.7 to 1.9 m at the shoulders and weigh 300 to 540 kg.
Dromedary camels were originally native to the Middle East and the Horn of Africa. Today, they are found in many parts of the world, including India, Australia and the USA.
Bactrian Camels (Two Hump Camel)
Bactrian Camels, also know as Mongolian camels, can be identified by their distinctive twin humps. Because they live in colder climates, they have more hair, shorter legs, and more solidly built than their dromedary cousins. They are the largest species of camel and can weigh up to 1,000 kg.
Bactrian Camels are native to parts of Central Asia but are also found in China, India, Australia and the USA. Wild Bactrian camels are endangered, with only about 1,000 surviving in the wild. There are about a million domesticated Bactrian camels.
Camel Characteristics What Does a Camel Look Like?
Camels have long, curved necks. They have large eyes with excellent vision, which allows them to spot danger 4-5 kilometres away. The eyes sit below prominent eyebrow ridges and bushy eyebrows that protect its eyes from the sun. It has long double-layered eyelashes too to keep the sun and sand out of its eyes. Besides its outer eyelids, the camel also has an inner eyelid, called a nictitating membrane, composed of a thin membrane that allows it to see during a sandstorm. Camels have a good sense of smell and can close their nostrils to keep out blowing sand. Its nose has special nasal cavities to moisten air on the way in, trap moisture going out. Their ears are small and rounded with hair inside and out to prevent sand from entering its ears.
Camels have large, tough prehensile lips, with the upper lip split into two halves, which enables them to pick at dry and thorny desert vegetation. Their incisors and canine teeth grow throughout life. Male camels foam at the mouth when excited and have a soft palate (upper part of the inside of the mouth) that they can inflate to produce a deep pink sac that dangles from one side of the mouth and is used to attract females during the mating season. It is often mistaken for the animal’s tongue.
Camels spit when provoked. Actually, they aren't true ‘spitters’ like humans. Instead, they are more ‘flingers’. A camel’s spit is not composed of only saliva, but instead, the camel burps up some of its stomach contents into its mouth, mixes it with saliva, and then flings mixture from its flappy lips at its opponent. This foul-smelling sticky concoction is definitely not something you want to be covered in.
The camel has a single hump or a double hump on top of its back. Contrary to popular belief, it does not store water in its hump. Instead, this hump is composed of fibrous tissue and fat. It is a store of energy. The size of the hump varies depending on the fat stored in it. The hump is at least 20 cm high and when fully extended, it can store up to 36kgs of fat, which the camel can break down into water and energy when required. The hump nearly disappears and flops over when the fat store is used up.
Even though the top of a camel’s hump is the highest point of the animal's body, its height is measured at the shoulders. This is because the height of the hump varies, going up and down depending on its store of fat.
Camel Walking and Running
The camel has long, powerful legs with large two-toed feet that have soft thick and flexible footpads that spread out, allowing them to easily walk on soft sand and gravel, but these special adaptations provide little traction on slippery and muddy surfaces. Unlike most animals, camels move both legs on one side of the body at the same time (lift both left legs - lift both right legs, rather than one left and one right leg like most other animals). The walking stride is long and slow, with the body supported for much of each stride on the grounded legs on one side of the body. Camels can run at 40 kph for extended periods of time and can sprint at 67 km/h for short periods. They can walk up-to 160km a day.
Camel's Special Adaptations
Camels have several special adaptations especially suited for their dry environments.
• Camels have a third clear eyelid to protect their eyes and can close their nostrils during sandstorms.
• Camels can endure temperatures from -29°C to over 49°C.
• Their long legs keep their bodies elevated further away from the hot ground to reduce overheating.
• They can adjust their body temperature in a range of 34-40°C. By doing this, the animal can minimise sweating and therefore conserve body fluids.
• To conserve water, camels only sweat when their body temperature reaches 41-42°C. Until that temperature threshold is reached, they allow their body temperature to rise with that of their environment.
• The camel's red blood cells are oval, which allows them to flow better even when the animal is in a dehydrated state.
• It can tolerate a loss of water equal to over 30% of body weight (a human can only survive a 15% loss)
• Its urine is highly concentrated and is its dung is dry to save water.
Camels thrive in arid and semi-arid areas. Their natural habitats are in the Middle East, India, Pakistan, Afghanistan, and Central Asia. They are non-territorial and wander widely, travelling as much as 70 km a day depending on the availability food, water, and summer shade. During winter, camels prefer open plains, salt marshes, and lakes. In summer they prefer dense bush country with trees for shade.
The largest population of wild camels in the world live in the deserts of central Australia. They inhabit the desert interior of Australia, including the Great Sandy, Gibson, Great Victoria, and Simpson deserts in the states of Western Australia, the Northern Territory, western Queensland, and northern South Australia – an area of 3.3 million sq km.
Camels are herbivores that eat almost any available plant. They are definitely not picky about what plants they eat. They graze on grasses and forbs and browse on shrubs and trees to a height of about 3.5 m. While browsing, they use their thick prehensile lips to grasp their food, breaking off branches or stripping off leaves in one movement. Camels have an interesting foraging characteristic where they tend to eat only a few leaves from each plant. This type of feeding behaviour is definitely beneficial to the plant, as it reduces the stress on the plant and also leaves sufficient sustenance other herbivores. This foraging behaviour is believed to have evolved to prevent killing its food source by over-grazing and also to reduce their intake of any particular plant toxin by foraging on the widest variety of foliage.
A camel can survive a week or so without water. It can drink as much as 145 litres of water in one drinking session at a rate of about 10 litres per minute.
It can last for several months without food.
It is claimed that a starving camel will eat almost anything including bones, ropes, leather products, and even canvas tents.
Camels feed for 6-8 hours each day. Being ruminants, like cows, they spend another 6-8 hours each day ruminating (chewing the cud). They do this by regurgitating food from their stomachs to chew it again. Where the food they consume is high in water content, camels don’t need to drink water.
When food and water become scarce, the camel extracts energy and water from fat stored in its hump. The longer a camel goes without eating or drinking, the more visibly deflated its hump becomes.
A camel gives birth to a single calf about 12-14 months after mating. Just before giving birth, she removes herself from the herd and withdraws to a quiet place covered with vegetation to give birth. The newborn calf has no hump when it is born Instead, it has some loose skin on top of its back covered with curly hair were the hump will eventually form. The new calf can walk within half an hour. The mother and calf remain away from the herd for two weeks before they return. The calf is nursed for about 10-18 months, after which it becomes totally independent.
The infant mortality rate amongst baby camels is about 30%. It is claimed that nearly half the deaths are caused by aggressive male camels that forcefully separate females from their calves to mate with them.
A camel reaches adulthood in about 7 years. The average life expectancy of a camel is 40 to 50 years.
Because of their large size and the arid environments in which they live, camels have no natural predators. Deaths are primarily caused by old age or prolonged drought where the animals starve to death. There are also reports of infanticide, where bulls during mating season are openly hostile towards newborn calves, forcing the cow away from the calf after birth, leading to the death of the calf.
From time to time, various local and state governments initiate culling campaigns to reduce camel numbers. Camels are also harvested for their meat, which is used in pet food.
