You'll find giraffes in South Saharan Africa. Note: in prehistoric
times this single species ranged over most open areas in Africa. The giraffe
range began to shrink 1400 years ago to its present size.
They like it dry: Giraffes live in the dry savannahs and
open woodlands, usually associated with scattered acacia growth.
They concentrate near rivers during the dry season, but scatter widely
into deciduous woodlands during the rainy season.
Just browsing: These animals are browsers, plucking leaves, buds
and fruits from trees such as acacia, momosa and wild apricot.
By spreading their forelegs and extending them forwards, giraffes can
collect some food (fallen fruits, grasses) from the ground. Giraffes drink
only occasionally if water is available, when unavailable they can survive
several weeks without drinking.
Big hearted to be sure: Giraffes, with their extremely long necks,
have a higher blood pressure than any other land animal. This high pressure
is needed to force blood up their long neck to their brain.To maintain
the pressure, a giraffe's heart is two feet long, weighs 25 pounds and
has walls three inches thick.The tallest giraffe on record lived in a
London zoo and attained a height of 20 feet.
Giraffes exhibit considerable variations in hair color and pattern, the
most common being the reticulated pattern (square block pattern).
*Our giraffes fall into a rarer group called Masai, which have irregular
blotchy patterning.
Live long lives: Full size is usually attained in five years for
males and seven years for females. In the wild, giraffes live about 26
years. The record age occurred in captivity: 36 years, 2 months.
Babies and stuff: Females become sexually mature in 3.5 years:
males mature a year later. Females are able to reproduce up to age twenty.
Giraffes will breed over most of their range at any time of the year.
Their gestation period averages 457 days (15+ months). Usually, mothers
give birth to a single calf, but twins are known to occur.
A newborn calf can usually stand as soon as twenty minutes after birth
and will begin to nurse in about an hour. The calf will nurse for up to
13 months and may remain with the mother for another 2-3 months after
weaning.
A cross between a camel and leopard? The species name cameleopardalis,
(camel leopard) was derived from the first Europeans to see the giraffe
who thought it was the offspring of a camel and a leopard.
Active mostly in the evening and early morning, they often rest during
the heat of the day. While inactive, they will doze standing up. While
dozing, their necks are often held extended forward. In deep sleep, the
neck is curved down and back to rest on a hind leg. They may lie down
for a while, though in the wild this would make them particularly vulnerable
to lion attack.
The giraffes' senses of smell, hearing and vision are acute. They may
have the keenest eyesight of any of the African big game species. Their
great height increases their visual range.
Giraffes defend themselves by fleeing or, if standing ground to protect
their young, by kicking with either fore or hind legs. They can also strike
with their head or upper neck by swinging their head against a foe. While
usually observed singularly or in small groups, giraffes with young may
band together and share "baby sitting" duties; a few adults remain with
the young while others go off to feed or drink.
Could run in the Derby: Though their feet are large, their long
legs and weighty body requires that giraffes remain on mostly firm ground.
In mud or swampy conditions they bog down easily. When walking, the legs
on one side advance at the same time (pacing). When running, the hind
legs are extended forward outside the forelegs. Over moderate distances,
if pressed, a giraffe can outrun a horse. When not pressed but merely
loping, it can cover great distances without tiring.
More on giraffes: While not endangered, giraffes have been wiped
out by hunting and climatic changes in large areas of their range. The
greatest concentration to be found today is on Tanzania and nearby areas.
They do well in game preserves and similar areas protected from poachers
and trophy hunters.
Status: Threatened.
