The first time I was introduced to a Zebra was by
my artisan uncle. He showed me a wooden sculpture of
a Zebra, beautifully painted with black and white stripes.
I handled and examined the wood carving as he described
it. Later, as I was herding my father's cattle during
one of the school holidays, I saw the real Zebra and
recognized it immediately. Yes, the black and white
stripes are the trade mark of a Zebra. You will recognize
it anytime, anywhere and at any age above three.
Plain Zebra,Grev's Zebra and Mountain Zebra are the
three Zebra species that are known to exist. Africa
is the home of all these species. The Plains Zebra are
the most plentiful and can be found virtually anywhere
on the Kenyan plains and other parts of East Africa
while the Grevy's Zebra are mostly found in Northern
Kenya. The Plains Zebra and Grev's Zebra of Kenya have
been known to coexist in the same habitat. The Mountain
Zebra have their habitat in Southern and Southwestern
Africa. Zebras are herbivorous and can grow up to 900
lb (410kg) or more. Being social animal, they move in
herds of different sizes.
While the black and white stripe pattern makes the Zebra
spectacular, the amazing facts about the stripes go
beyond the beauty. For years scientists have argued
about why the zebra has distinctive black and white
stripes. The theories rotate around Zebra Identity and
Camouflage. This article discusses these amazing theories:
- Description: Whether the Zebra's stripes are white
on a black background, as some people say, or vice versa
is academic. I leave it at that.
- Identity: At first glance Zebras in a herd might all
look alike, but their stripe patterns are as distinctive
as fingerprints are in humans. There are, indeed, scientific
methods that can identify individual Zebras by comparing
patterns, stripe widths and colour. Further proof that
Zebra stripes are identity marks is provided by their
behavior. For example, on rare occasions when unstriped
Zebras are born, they tend to be ignored by the rest
of the herd, confirming at least, that Zebra stripes
are a passport to Zebra society. Also, when a foal is
born, the mother keeps all other Zebras away from it
for two to three days, until it learns to recognize
her by sight, voice and smell.
- Camouflage: Scientists believe the Zebra's
stripes provide camouflage in the following manner:
- The vertical stripes of a Zebra will resemble tall
grass, save for the colour-grass is neither black nor
white. To a colour blind preditor like a Lion,therefore,
the Zebra will perfectly merge with the grass and be
invisible especially when it is not moving. - The Zebra
stripe pattern forms a discolouration that breaks up
the body outline. A herd of Zebras close together may
thus appear like one large animal. The advantage of
all this to the Zebra is best appreciated when you consider
that the main predator for the Zebra is the lion, which
is colour blind. Now, in attack, the lion must first
identify the target, usually a young, old or a weakened
Zebra. The Lion's eyes must then lock on the target
Zebra. If, for whatever reason, the Lion is unable to
achieve any of these steps, then,its stealth and ambush
attack strategy is likely to be in vain.
The Zebra's black and white stripes are its trade mark.
Just by seeing a quality wood carving of a zebra, for
example, it is possible to easily and confidently identify
the real Zebra at first sight. There is ample evidence
that the Zebra stripes act as its identity and camouflage
tool.
