  Giraffe
 </title>
 <shortdesc>
  <ph id="2">
   The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal, the tallest of all land-living animal species, and the largest ruminant.
  </ph>
  <ph id="3">
   Males can be 4.8 to 5.5&amp;#160;metres (16 to 18 feet) tall and weigh up to 1,700&amp;#160;kilograms (3,800&amp;#160;pounds).
  </ph>
  <ph id="4">
   The record-sized bull, shot in Kenya in 1934, was 5.87&amp;#160;m (19.2&amp;#160;ft) tall and weighed approximately 2,000&amp;#160;kg (4,400&amp;#160;lb).
  </ph>
  <ph id="5">
   Females are generally slightly shorter, and weigh less than the males do.

   Etymology
  </title>
  <refbody>
   <p id="5">
    <ph id="13">
     The species name camelopardalis (camelopard) is derived from its early Roman name, where it was described as having characteristics of both a camel and a leopard.
    </ph>
    <ph id="14">
     The English word camelopard first appeared in the 14th century and survived in common usage well into the 19th century.
    </ph>
    <ph id="15">
     The Afrikaans language retained it.
    </ph>
    <ph id="16">
     The Arabic word الزرافة ziraafa or zurapha, meaning "assemblage"
    </ph>
    <ph id="17">
     (of animals), or just "tall", was used in English from the sixteenth century on, often in the Italianate form giraffa.

   Taxonomy and evolution
  </title>
  <refbody>
   <p id="7">
    <ph id="19">
     Giraffids evolved from a 3&amp;#160;metre (10&amp;#160;ft) tall antelope-like mammal which roamed Europe and Asia 30-50 million years ago.
    </ph>
    <ph id="20">
     The earliest giraffid was the Climacoceras, which still resembled deer, having large antler-like ossicones.
    </ph>
    <ph id="21">
     It first appeared in the early Miocene period.
    </ph>
    <ph id="22">
     As the lineage went on the genuses Palaeotragus and Samotherium appeared in the early to mid-Miocene.
    </ph>
    <ph id="23">
     One species of Palaeotragus developed more giraffe-like ossicones.
    </ph>
    <ph id="24">
     They both were tall at the shoulder but still had short necks.
    </ph>
    <ph id="25">
     For there the genus Giraffa evolved in the Pliocene period and Okapia evolved in the Pleistocene.
    </ph>
    <ph id="26">
     The modern long-necked giraffe, Giraffa camelopardalis, appeared 1 million years ago.

    <ul>
     <li>
      Reticulated or Somali Giraffe (G.c. reticulata) — large, polygonal liver-coloured spots outlined by a network of bright white lines. The blocks may sometimes appear deep red and may also cover the legs. Range: northeastern Kenya, Ethiopia, Somalia.

      Further, some scientists regard all populations except the Masai Giraffes as a single subspecies.

      Though giraffes of these populations interbreed freely under conditions of captivity, suggesting that they are subspecific populations, genetic testing published in 2007 has been interpreted to show that there may be at least six species of giraffe that are reproductively isolated and not interbreeding, even though no natural obstacles, like mountain ranges or impassable rivers block their mutual access.

      Both sexes have horns, although the horns of a female are smaller.

      The prominent horns are formed from ossified cartilage and are called ossicones.
     </ph>
     <ph id="49">
      The appearance of horns is a reliable method of identifying the sex of giraffes, with the females displaying tufts of hair on the top of the horns, where as males' horns tend to be bald on top — an effect of necking in combat.
     </ph>
     <ph id="50">
      Males sometimes develop calcium deposits which form bumps on their skull as they age, which can give the appearance of up to three further horns.

      The pace of the giraffe is an amble, though when pursued it can run extremely fast.

     <ph id="60">
      It can not sustain a lengthy chase.
     </ph>
     <ph id="61">
      Its leg length compels an unusual gait with the left legs moving together followed by right (similar to pacing) at low speed, and the back legs crossing outside the front at high speed.

      When hunting adult giraffes, lions try to knock the lanky animal off its feet and pull it down.

      Giraffes are difficult and dangerous prey though, and when attacked the giraffe defends itself by kicking with great force.

      Modifications to the giraffe's structure have evolved, particularly to the circulatory system.
     </ph>
     <ph id="68">
      A giraffe's heart, which can weigh up to 10&amp;#160;kg (22&amp;#160;lb) and measure about 60&amp;#160;cm (2&amp;#160;ft) long, has to generate around double the normal blood pressure for an average large mammal in order to maintain blood flow to the brain against gravity.
     </ph>
     <ph id="69">
      In the upper neck, a complex pressure-regulation system called the rete mirabile prevents excess blood flow to the brain when the giraffe lowers its head to drink.
     </ph>
     <ph id="70">
      Conversely, the blood vessels in the lower legs are under great pressure (because of the weight of fluid pressing down on them).
     </ph>
     <ph id="71">
      In other animals such pressure would force the blood out through the capillary walls; giraffes, however, have a very tight sheath of thick skin over their lower limbs which maintains high extravascular pressure in exactly the same way as a pilot's g-suit.

     Reproduction
    </title>
    <p id="27">
     <ph id="83">
      Giraffe gestation lasts between 14 and 15 months, after which a single calf is born.
     </ph>
     <ph id="84">
      The mother gives birth standing up and the embryonic sack usually bursts when the baby falls to the ground.
     </ph>
     <ph id="85">
      Newborn giraffes are about 1.8&amp;#160;m (6&amp;#160;ft) tall.
     </ph>
    </p>
    <p id="28">
     <ph id="86">
      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.
     </ph>
     <ph id="87">
      The young can fall prey to lions, leopards, spotted hyenas, and wild dogs.
     </ph>
     <ph id="88">
      It has been speculated that their characteristic spotted pattern provides a certain degree of camouflage.
     </ph>
     <ph id="89">
      Only 25 to 50% of giraffe calves reach adulthood; the life expectancy is between 20 and 25 years in the wild and 28 years in captivity (Encyclopedia of Animals).

     Necking
    </title>
    <p id="30">
     <ph id="91">
      As noted above, males often engage in necking, which has been described as having various functions.
     </ph>
     <ph id="92">
      One of these is combat.
     </ph>
     <ph id="93">
      Battles can be fatal, but are more often less severe.
     </ph>
     <ph id="94">
      The longer the neck, and the heavier the head at the end of the neck, the greater the force a giraffe is able to deliver in a blow.
     </ph>
     <ph id="95">
      It has also been observed that males that are successful in necking have greater access to estrous females, so the length of the neck may be a product of sexual selection.
     </ph>
    </p>
    <p id="31">
     <ph id="96">
      After a necking duel, a giraffe can land a powerful blow with his head — occasionally knocking a male opponent to the ground.
     </ph>
     <ph id="97">
      These fights rarely last more than a few minutes or end in physical harm.
     </ph>
    </p>
    <p id="32">
     <ph id="98">
      Another function of necking is affectionate and sexual, in which two males will caress and court each other, leading up to mounting and climax.
     </ph>
     <ph id="99">
      Same sex relations are more frequent than heterosexual behaviour.
     </ph>
     <ph id="100">
      In one area 94% of mounting incidents were of a homosexual nature.
     </ph>
     <ph id="101">
      The proportion of same sex courtships varies between 30 and 75%, and at any given time one in twenty males will be engaged in affectionate necking behaviour with another male.
     </ph>
     <ph id="102">
      Females, on the other hand, only appear to have same sex relations in 1% of mounting incidents.

     Stereotypic behavior
    </title>
    <p id="34">
     <ph id="104">
      Many animals when kept in captivity, such as in zoos, display abnormal behaviours.
     </ph>
     <ph id="105">
      Such unnatural behaviours are known as stereotypic behaviours.
     </ph>
     <ph id="106">
      In particular, giraffes show distinct patterns of stereotypic behaviours when removed from their natural environment.
     </ph>
     <ph id="107">
      Due to a subconscious response to suckle milk from their mother, something which many human-reared giraffes and other captive animals do not experience, giraffes resort instead to excessive tongue use on inanimate objects.
     </ph>
    </p>
    <p id="35">
     <ph id="108">
      Due to the obvious social and cultural discomfort associated with the addition of milk delivery devices, animal enclosures are often enriched with other stimuli, such as food and mental distractions (toys, scent markings etc.).
     </ph>
     <ph id="109">
      This operates as a distraction, removing the giraffe’s focus from its instinctual tendencies towards suckling, resulting in tongue lolling and licking of objects in close proximity.

     The giraffe browses on the twigs of trees, preferring trees of the genus Mimosa; but it appears that it can live without inconvenience on other vegetable food.
    </ph>
    <ph id="112">
     A giraffe can eat 63&amp;#160;kg (140&amp;#160;lb) of leaves and twigs daily.
    </ph>
    <ph id="113">
     As ruminants, they first chew their food, swallow for processing and then visibly regurgitate the semi-digested cud up their necks and back into the mouth, in order to chew again.
    </ph>
    <ph id="114">
     This process is usually repeated several times for each mouthful.
    </ph>
    <ph id="115">
     In captivity they can sense food when humans are around and will ask for some by sticking their head up close to them and extending their tongue out.

     A giraffe will clean off any bugs that appear on its face with its extremely long tongue (about 45&amp;#160;cm/18&amp;#160;in).
    </ph>
    <ph id="117">
     The tongue is tough on account of the giraffe's diet, which can include thorns from the trees that they eat.
    </ph>
    <ph id="118">
     In Southern Africa, giraffes feed on all acacias, especially Acacia erioloba, and possess a specially-adapted tongue and lips that are tough enough to withstand, or even ignore, the vicious thorns of this plant.

      In the wild, this hazard is reduced by the presence of trees; as well, the giraffe's natural habitat range has an extremely low occurrence of lightning -- NASA's satellite lightning detection system indicates that the area receives an average of less than one cloud-to-ground flash per square kilometre per year.
