While
in Dunhuang, on the edge of the Gobi desert, we not only rode one of these
camels, we
-->saw them
running wild, or at least completely on their own, unfenced and
unmonitored. The only truly wild camels
that still exist are Bactrian camels. These herds survive in the Gobi Desert of
Mongolia and China.
Bactrian
camels have two humps rather than the single hump of their Arabian relatives.
The humps function to store fat which can be converted to water and energy when
sustenance is not available. These humps give camels their legendary ability to
endure long periods of travel without water, even in harsh desert conditions.
As their fat is depleted, the humps become floppy and flabby. They could go 40 days without water over the
Gobi desert, making them a popular pack animal during the hey day of the Silk
Road.
Bactrian
camels live in Central and East Asia's rocky deserts. Temperatures in these
locales are hot—over 100°F-- in summer. Yet they can also drop
to –20°F in winter. They have developed special adaptations to allow
them to survive in such a brutal environment. One is a thick, shaggy coat that
protects them in winter and falls away as seasons change and temperatures rise. They rarely sweat, helping them conserve
fluids for long periods of time. In winter, plants may yield enough moisture to
sustain a camel without water for several weeks. Like
Arabian camels, Bactrians' nostrils close to keep sand at bay, and their bushy
eyebrows and two rows of long eyelashes protect their eyes. Big, flat footpads
help them navigate the rough rocky terrain and shifting desert sands without
sinking under their own massive bulk or the weight of heavy packs.
