For most creatures...
the key to surviving the desert...
is to be on constant move.
An animal that is unusual to see in this geography.
The desert giraffe.
The land here bears traces of River Hoanib...
which once flowed through here...
but there is no sign of water.
The few plants capable of reaching groundwater...
are spread out few and far between.
Desert giraffes must find food.
They surpassed dozens of hills...
walked for hours under the scorching sun...
and crossed riverbeds that have been 
dry for thousands of years.
Finally...
They reach an oasis in the desert.
It is time to fill their empty stomachs.
Exposed to such heat...
moisture from plants is not enough for the giraffes.
They must find a waterhole after eating.
Giraffes close to waterholes are not so worried...
about looking for food and water.
They can gorge on leaves in high branches...
that are unreachable by other creatures.
Having said that...
an abundance of resources....
means an abundance of predators.
They must move in groups to quench their thirst.
The time when a giraffe is most vulnerable.
Members of the herd are alert to threats.
They will drink in turns.
