Giraffes
Introduction:
Giraffes are the tallest mammals in the world, and are
known for the beautiful pattern on their skin - large,
brown spots on a yellowish background. There are nine
generally accepted subspecies, differentiated by colour
and pattern variations, and range.
Location:
Africa is the only continent in the world where giraffes
live. They like grasslands and woodlands - flat, grassy
areas in amongst trees and bushes. In Africa, these areas
are called savannahs. They are most popular in Niger,
located mostly on the area of Sahara Desert in North Africa.
There are also found in Kenya, Uganda, and Tanzania on
the east of the continent, and South Africa, and Botswana
in the far south.
Size:
Males can grow up to 18 ft (5.5 m) tall, and can weigh
up to 3,000 lbs (1,360 kg). Their bodies from front to
hind legs are approximately 5 ft (1.5 m), with a tasselled
tail measuring an additional 3 ft (1 m). Their neck usually
measures 8 - 10 ft (2.5 - 3 m), and their long, thin,
hoofed legs are about 5 - 6 ft (1.5 - 2 m) tall. A giraffe's
head is about 2 ft (0.6 m).
Food:
Giraffes only eat plants, amongst their favourites are
the leaves from mimosa and acacia trees. An adult giraffe
can eat up to 140 lbs (63 kg) of leaves and plants a day.
Giraffes first chew their food, swallow for processing
and then visibly regurgitate the semi-digested food up
their necks and back into the mouth, in order to chew
again. This process is usually repeated several times
for each mouthful. Similar to camels, they can go for
a long time without water, but when they do drink, they
can ingest up to 12 gallons of water at once.
Life Cycle:
Giraffe gestation lasts between 14 to 15 months, after
which a single calf is born. The mother gives birth standing
up and the embryonic sack usually bursts when the baby
falls to the ground. Newborn giraffes are about 6 ft (1.8
m) tall. Within a few hours of being born, calves can
run around and are indistinguishable from a week-old calf.
However, for the first two weeks, they spend most of their
time lying down, guarded by the mother. While mothers
feed, the young are kept in small nursery groups. The
young, however, can fall prey to lions, leopards, hyenas,
and African wild dogs. Only 25 to 50% of giraffe calves
reach adulthood. Their life expectancy is between 20 and
25 years old in the wild.
Interesting Facts:
· The giraffe has one of the shortest sleep
requirements of any mammal, which is between 10 minutes
and two hours in a 24-hour period, averaging 1.9 hours
per day.
· They are gentle animals, who like a peaceful
and quiet life, and they almost never make any noise.
Only sometimes will they grunt or snort to communicate
each other.
· Their long legs make giraffes excellent
runners - they can run up to 55 km (35 miles) per hour.
· The pattern of each giraffe is unique, and
there are no two identical giraffes in the world.
· They are related to deer and cattle.
· A giraffe's spots get darker with age.
· Giraffes are non-territorial, social animals
and they travel in large herds.
Population & Predators:
Although adult giraffes don't get attacked very often
due to their size, speed and camouflaged skin, predators
such lions, hyenas, and leopards are their biggest enemies.
Young calves are easier to catch, and despite their mother's
care, more than half of them fall prey to lions and hyenas.
In West Africa, the giraffe population is increasingly
shrinking, however, the populations in eastern and southern
Africa are stable. Giraffe are a protected species in
most of their range.
Help Protect Their Environment:
· Due to the increasing spread of the desert
in West Africa, and the increasing need to clear land
for agriculture, it can be said that habitat destruction
is the greatest threat to giraffes and many of Africa's
other large animals. The combination of hunting and habitat
loss have driven giraffes to extinction in a number of
countries, including Mauritania, Senegal, and possibly
Mozambique and Mali. The future of giraffes and Africa's
other famed plains animals lies in careful conservation
of extensive habitats, both on park and private lands.
