THE A-Z OF CAMELS
The ancestors of the modern camel lived
millions of years ago in North America and wandered during one of the last
ice-ages across the Alaskan 'land bridge' to Asia and eventually Africa.
In Asia, two groups separated to become the two chief types of camel known
today: the one humped Dromedary and the two-humped, shorter-legged
Bactrian camel. Only the Bactrian camel can still be found rarely in the
wild, roaming the Gobi desert.
In Africa the wild dromedary became extinct by about 5000
years ago. He reappeared again 3100 ago domesticated by frankincense
traders, who trained the gangly cud-chewer to make the long and arduous
journey from southern Arabia to the northern regions of the Middle East,
the camel went on to become the desert dweller's primary source of
transport, shade, milk, meat, wool and hides.
In many
parts of Africa and
Asia
today, camels still pull ploughs, turn waterwheels and transport people
and goods to market along desert routes impassable by wheeled vehicles.
To appreciate the unique contribution that
the Arabian camel has made to the people and history of desert lands,
here's a comprehensive fact-pack on the special characteristics, body
structure and behavior patterns of this amazing creature.
|
Ata Allah,
God's gift |
The Bedouin name for Camelus
dromedarius, the 'one-hump' dromedary, also known as the Arabian
camel. |
|
|
|
Behaviour |
Unpredictable at best. Camels have
the reputation of being bad-tempered and obstinate creatures who spit
and kick. In reality, they tend to be good-tempered, patient and
intelligent. The moaning and bawling sound they make when they're
loaded up and have to rise to their feet is like the grunting and
heavy breathing of a weight-lifter in action, not a sign of
displeasure at having to do some work. |
|
|
|
Body temperature |
Camels do not pant, and they
perspire very little. Humans start to sweat when the outside
temperature rises above the normal body temperature of 37° C, but the
camel has a unique body thermostat. It can raise its body temperature
tolerance level as much as 5° C before perspiring, thereby conserving
body fluids and avoiding unnecessary water loss. No other mammal can
do this. Because the camel's body temperature is often lower than air
temperature, a group of resting camels will even avoid excessive heat
by pressing against each other. |
|
|
|
Colour |
Camels come in every shade of brown,
from white-cream to almost black. |
|
|
|
Ears |
A camel's ears are small, but its
hearing is acute - even if, like the donkey or basset hound, it
chooses to pay no attention when given a command! A camel's ears are
lined with fur to filter out sand and dust blowing into the ear canal. |
|
|
|
Eyes |
A camel's eyes are large, with a
soft, doe-like expression. They are protected by a double row of long
curly eyelashes that also help keep out sand and dust, while thick
bushy eyebrows shield the eyes from the desert sun. |
|
|
|
Feet |
Camels have broad, flat, leathery
pads with two toes on each foot. When the camel places its foot on the
ground the pads spread, preventing the foot from sinking into the
sand. When walking, the camel moves both feet on one side of its body,
then both feet on the other. This gait suggests the rolling motion of
a boat, explaining the camel's 'ship of the desert' nickname. |
|
|
|
Food |
A camel can go 5-7 days with little
or no food and water, and can lose a quarter of its body weight
without impairing its normal functions. These days, camels rely on man
for their preferred food of dates, grass and grains such as wheat and
oats, but a working camel traveling across an area where food is
scarce can easily survive on thorny scrub or whatever it can find -
bones, seeds, dried leaves, or even its owner's tent! |
|
|
|
Hair |
All camels moult in spring and have
grown a new coat by autumn. Camel hair is sought after world-wide for
high-quality coats, garments and artists' brushes, as well as being
used to make traditional Bedouin rugs and tents. A camel can shed as
much as 2.25 kilos/5lbs of hair at each moult. |
|
|
|
Hard skin |
Thick callus-like bare spots of dry
skin appear on a camel's chest and knee joints when the animal reaches
five months of age. These leathery patches help support the animal's
body weight when kneeling, resting and rising. |
|
|
|
Height |
A fully-grown adult camel stands
1.85m at the shoulder and 2.15m at the hump. |
|
|
|
Hump |
Contrary to popular belief, a camel
does not store water in its hump. It is in fact a mound of fatty
tissue from which the animal draws energy when food is hard to find.
When a camel uses its hump fat for sustenance, the mound becomes
flabby and shrinks. If a camel draws too much fat, the small remaining
lump will flop from it's upright position and hang down the camel's
side. Food and a few days' rest will return the hump to its normal
firm condition. |
|
|
|
Legs |
A camel's long, thin legs have
powerful muscles which allow the animal to carry heavy loads over long
distances. A camel can carry as much as 450kg, but a usual and more
comfortable cargo weight is 150kg. It is usual for a camel to work as
a beast of burden for only six to eight months of the year; the
remainder of the time it needs to rest and recuperate. |
|
|
|
Life span |
After a gestation periods of 13
months, a camel cow usually bears a single calf, and occasionally
twins. The calves walk within hours of birth, but remain close to
their mothers until they reach maturity at five years of age. The
normal life span of a camel is 40 years, although a working camel
retires from active duty at 25. |
|
|
|
Meat |
The best camel meat comes from young
male camels. It is regarded as a delicacy in the Arabian diet, and is
gaining popularity in arid lands where it is difficult to herd sheep,
cattle and goats. Although it makes for tough chewing, the taste is
not unlike beef. |
|
|
|
Milk |
Camel's milk is much more nutritious
than that from a cow. It is lower in fat and lactose, and higher in
potassium, iron and Vitamin C. It is normally drunk fresh, and the
warm frothy liquid, heavy and sweet, is usually an acquired taste for
the Western palate. Most Saudi Arabian camels are females reared for
their milk in dairy herds. |
|
|
|
Mouth |
The camel has a large mouth, with 34
sharp teeth. They enable the animal to eat rough thorny bushes without
damaging the lining of its mouth, and can be used as biting weapons
against predators if need be. A camel gulps down its food without
chewing it first, later regurgitating the undigested food and chewing
it in cud form. |
|
|
|
Nose |
A camel's nasal passages are
protected by large muscular nostrils that can be opened and closed at
will. When a camel twitches its nose, it is cooling the incoming air
and condensing moisture from its outgoing breath. |
|
|
|
Speed |
Normal 'amble speed' for a walking
camel is 5kph; a working camel will typically cover 40km a day. Racing
camels can reach 20kph at the gallop. |
|
|
|
Tail |
A camel's rope-like tail is over
50cm long. |
|
|
|
Water |
Camels need very little water if
their regular diet contains good, moisture-rich pasture. Although
camels can withstand severe dehydration, a large animal can drink as
much as 100 liters in ten minutes. Such an amount would kill another
mammal, but the camel's unique metabolism enables the animal to store
the water in its bloodstream. |
|
|
|
Weight |
A fully-grown camel can weigh up to
700kg. |
