This document contains information about various animals found in desert environments, including the desert fox, camel, red-necked ostrich, roadrunner, and Dorcas gazelle. It provides details on the physical characteristics and adaptations of each species that allow them to survive in desert conditions with little water and extreme temperatures. The document also discusses general characteristics of deserts and the evolution of cacti as plants adapted to desert environments.

3. DESERT FOX
is a species of carnivorous mammal of the
Canidae family that inhabits the Sahara
desert and Sinai peninsula. With its
characteristic ears, it is the smallest species
in its family. Their fur, ears and kidney
function are adapted to the physical
conditions of the desert: extreme
temperatures and water scarcity. The ears
serve as a blood ventilation and cooling
system that helps it withstand the high
temperatures and extreme desert climate.
The term fennec comes from the Arabic,
which means fox, and the specific epithet,
zerda, which comes from the Greek, refers
to its dry habitat (XeroS) . Other authors
propose the meaning of “astute” for the
translation of zerda in Greek

4. CAMEL
Camelus is a genus of artiodactyl
mammals in the family Camelidae
that includes the three living
species of the family originating in
the Old World, which are popularly
called camels and dromedaries.
They are ungulate animals native
to dry and desert areas of Asia

5. RED NECKED OSTRICH
It is the most robust of the ostrich
subspecies (and at the same time
of all the current birds), as well as
the fastest on land, and the one
that best supports the lack of water
(being reasonable for being a dry
habitat animal). Living up to its
name, the coloration of its neck and
legs is reddish pink, more intense in
males during the rutting season

6. ROADRUNER
The roadrunners are birds that
live in the desert, about 60
centimeters long, which with
their brownish gray plumage,
speckled with black and white
spots, are characterized by
having a long beak, an
extraordinary feathered crest
and an elongated tail. Although it
is equipped with wings, they only
fly over short distances,
however, the muscular power of
its legs allows it to develop a
speed of 40 kilometers per hour
when they run.

7. DORCAS GAZELLE
The Dorca gazelle is similar in appearance (but
smaller) to the mountain gazelle in that they are
closely related (Gazella gazella). The Dorca
Gazelle have longer ears and more curved horns.
Individuals belonging to the Sahara subspecies (G.
d. Osiris) have very pale colored coats. The white
underside is bordered by a brown stripe, above
which is a sand-colored stripe. The front and face
are darker than the body. The subspecies of
northern Sahara stripes become more ocher in
color, and have dark flanks and facial stripes.
Populations in Israel and throughout the Red Sea
are dark reddish in color. In the last century, the
Dorcas gazelle population was partially destroyed
in all the countries where they were found

8. DESERT
CHARACTERISTICS
The desert is a very frequent
bioclimatic landscape on the
Earth's surface, characterized by
its very low rainfall and low
presence of fauna and flora, given
the low humidity levels. Although
the traditional image of the sandy
desert refers to warm and
equatorial climates, the truth is
that those located on the Arctic
plateau or in the tundra also count
as deserts.

9. CACTUS
CACTUS is considered to have
evolved between 30 and 40 million
years ago. The American continent
was united with the others, but it was
gradually separated by continental
drift. The endemic species of the
New World must have developed
after this separation; the significant
distance was reached in the last 50
million years. This could explain the
non-existence of endemic cacti in
Africa: they evolved in America when
the continents had already
separated.
