The Giaraffe
Ancient cultures in Africa revered the
giraffe, as some modern cultures do today, and commonly depicted it
in prehistoric rock and cave paintings. Unknown outside of Africa,
early written records described the giraffe as "magnificent in
appearance, bizarre in form, unique in gait, colossal in height and
inoffensive in character."
The Giraffe moves about the
semi-arid regions in groups. Its height allows it to keep in contact
with other giraffes over large distances as well as spotting
predators from afar. It is not uncommon to see other animals
following a giraffe using it as an early predator warning system.
The Giraffe is vulnerable when drinking. It is a quiet
species although the males fight viciously for dominance over the
group.
The neck is so long the giraffe must spread its front
legs apart so its head can reach the ground to drink. It has
unusually elastic blood vessels with a series of valves that help
offset the sudden buildup of blood (and to prevent fainting) when the
head is raised, lowered or swung quickly.
The giraffe's high
shoulders and sloping back give the impression that its front legs
are much longer than the hind legs, but they are in fact only
slightly longer. The giraffe (as well as its short-necked relative
the okapi from Central African forests) has a distinctive walking
gait, moving both legs on one side forward at the same time. At a
gallop, however, the gait changes, and the giraffe simultaneously
swings the hind legs ahead of and outside the front legs, reaching
speeds of 35 miles an hour. Its heavy head moves forward with each
powerful stride, then swings back to stay balanced. Giraffes have
"horns" not true horns but knobs covered with skin and hair
above the eyes to protect the head from blows
Family:
Giraffidae
Size: 18 feet; weight: Up
to 3000 pounds.
Diet: Herbivorous
browsers. When protected, giraffes can flourish in areas where food
is abundant year round. Although they drink water when it's
available, they can survive where it is scarce. Giraffe occasionally
eat grass and fruits of various trees and shrubs, but their principal
food source is the acacia tree.
Habitat: Dry
savannah woodland. Giraffes are found in arid and dry-savanna zones
south of the Sahara, wherever trees occur.
Reproduction:
Single young born any time of the year. Gestation 15
months.
Lifespan: 28 years
Predators:
Humans
