Arabian Camel
One of the
only two remaining species within the genus Camelus still existing today, the
other one being the
Bactrian Camel
(fig.). Four more species in this genus
are today extinct. Though mostly found in North Africa and the Middle East, the
Arabian Camel also occurs in India, whilst the Bactrian Camel is native to the
steppes of central Asia and is commonly found in remote regions, such as
China's
Gobi Desert. The Arabian Camel, which is also commonly called
Dromedary, is known by the scientific name Camelus dromedarius and is with
an estimated 13 million of them the largest member of the camel family. It
probably originates from the Arabian Peninsula, but its domesticated form is
found from North Africa through to South Asia, with an introduced feral
population in Australia. In contrast to the Bactrian Camel, which has two humps
on its back, the Dromedary has only one. These humps are in fact large fat
reserves. Camels can drink up to 60-100 liters of water in just 10 minutes, which
-contrary to popular belief- they do not store in their humps, but in their
stomachs, from where they release it only slowly into the blood flow, preventing any damage that would occur with other mammals if they would drink such large quantities in such a short time. Unlike most other mammals, which mostly have thick and rounded blood platelets, those of camels are rather flat and oval-shaped, which makes them circulate much faster through the bloodstream, a feature which is said to help prevent dehydration. Consequently, camels can lose up to 30% of their body fluid before experiencing adverse consequences, whereas people and most other mammals can lose only about 10% of their body fluid, after which nausea will set in and even blindness or death may occur. In addition, the
camel is uniquely equipped with special adaptations, that allow it to go for
days without drinking, i.e. its nose humidifies dry air as it breaths in, then
de-humidifies it on the way out, thus conserving precious water, and
its body temperature can rise by 6 degrees Celsius before it even begins to
sweat. It also has thick fur, that reflects the sunlight during by day, allowing
it to endure the searing heat of the desert (fig.), whilst it keeps it warm at night,
when temperatures can be freezing cold. Both camel species have long been used as domesticated
draft (fig.)
and working animals (fig.),
and were an indispensible means of transportation (fig.)
in the cross-country trade per caravan over inhospitable terrain, such as
certain parts of the ancient
Silk Road. Due to its intrinsic role in the
history of India, the Arabian Camel is often found depicted in Indian art and
iconography (fig.).
