CONTENT SAMPLE:

The giraffe (Giraffa camelopardalis) is unique in being the only ungulate which possesses
four apparent horns—two small ones on the forehead and a pair of larger ones farther back on the
head. Moreover, giraffe horns, unlike those of bovids, lack a horny sheath. Instead, skin and
hair cover the ossicones. Nevertheless, they are true horns. In fact, it is known that the horns of
the giraffids and bovids are homologous (have arisen from the same primitive origins), and are
quite different from those of the cervid family or the pronghorn antelope. While they no longer
pierce the skin of an opponent, the blunt, knobby, skin-covered horns of the giraffe are able to
wound it seriously, because of the great weight and force which an adult giraffe can exert when
swinging his head and horns in attack.

Despite the fact that giraffes are the tallest living mammals, their necks have only the
usual seven vertebrae. Giraffes may be 3.5 m high at the shoulders. They feed almost entirely
on the leaves of tall trees, reaching as much as 5.5 m above the ground. They are able to go
without drinking water for many weeks. The giraffe is a good example of a highly specialized
animal, well-suited to its own natural environment.

Giraffes are shy, timid, naturally silent and inoffensive creatures which once ranged over
the greater part of the African continent south of the Sahara. They prefer dry habitats—
savannahs, plains and open wooded areas—where food is abundant. Giraffes are browsers and
feed almost exclusively on acacia, mimosa and wild apricots. Their exceedingly long necks
allow them to reach high into the trees for succulent leaves, and their tongues and prehensile,
hairy lips aid in plucking the leaves.

Like bovids, giraffes are ruminants. They usually feed in the evenings and early
mornings, then rest and chew their cuds during the heat of the day. They can go without water
for weeks at a time, but will drink freely if it is available. In order to drink, they must spread
their front legs wide apart and lower their heads to the water. It is at this time, when their heads
are lowered, that they are most vulnerable to attacks by lions and leopards, which, besides man,
are their principal predators.

Giraffes are gregarious and usually associate in small herds or family groups of 12 to 15
animals, including one adult male, several cows with calves, and a number of juveniles. Juvenile
males are allowed to remain with the group until they become old enough to compete with the
adult male. Then they are banished.

Giraffes have some of the keenest senses of the animal world: Their sense of smell and
hearing are acute, and they have the sharpest eyesight of all the large African herbivores.
Females are more cautious than males. When alarmed, the entire herd can lope off at speeds of
up to 50 km/h. When they run they have a rolling gait, produced because both legs on one side
move together, unlike the running movements of most animals.
