surrounding, they had to find ways to resist
the extremely high temperatures in the Namib and the Kalahari - the ground can heat up
to 80°C and more. Like insects they have become mainly nocturnal and hide away in holes,
between rocks or bury themselves in the sand during the heat of the day. To prevent
them from loosing too much water, lizards and snakes have a resistant skin, covered
with scales of horn, whereas turtles are protected by their thick shield of bone.
Some lizards have developed behaviour of positioning themselves differently towards
the sun, depending on the time of day, to control their body temperature with the angle
the sunbeams hit their body.
The following list of reptiles and insects of course doesn't show all kinds that can
be found on the Vogelstrausskluft, but gives an impression of some of the most interesting
or most common species.
Because of the harsh conditions life in the desert mainly takes place in
small dimensions. The major number of desert animals therefore is insects,
spiders or reptiles, of which only a small number is dangerous for a human.
Only sporadically seen during the day, the Kalahari at night awakens to life.
In the desert insects have two important advantages of all other species:
their small size and their firm exoskeleton. Due to their size insects are able
to find shelter from the sun or enemies even under stones or small plants, and
need only very little water to survive. In most cases the dewdrops that form every
morning on leaves or rocks suffice. The exoskeleton on the other side protects them
against loosing too much water due to evaporation and makes them resistant against
the high temperatures on the ground.
Although desert reptiles, like all other reptiles, are cold-blooded, and therefore
can adapt their body temperature to their
