The giraffe is a large, long-necked, African mammal belonging to the genus Gi-
         raffa, a member of the family Giraffidae. There are four* extant species, three with subspecies, each
         species distinguishable by its coat pattern. They are found in northern Chad, in South Africa in the
         south, and from Niger in the west to Somalia in the east. They are the tallest of all land mammals,
         with males (bulls) being upward of 5.5 metres tall and weighing around 1,930 kg. Females (cows)
         are slightly smaller. The ancestors of the present day giraffes are believed to have appeared around
                                                           34 million years ago.

                                                                t. thornicrofti
                                                           4. Reticulated giraffe (Giraffa reticulata)

                                                                Giraffes are exceptionally large animals with a
                                                           towering  neck,  2.4  metres  tall  with  a  short  hairy
                                                          mane running its full length. Their body is covered in
          Coat Patterns                                   a  bright  orangey  patterned  fur  coat,  and  supported
                                      by four sturdy but lanky legs. It has a metre long fly swatting tail with a
                                      long black hairy tuft at its tip. Both males and females have two 13.5cm
                                      conical skin-covered horns, called ossicones, on their heads. They have
                                      good  eyesight  and  sensitive  hearing.  Their  ears  are  large  and  it  can
                                      move them around to locate sounds. It has a long blunt snout, with a
                                      hairy flexible upper lip and its upper jaw has a hard palate instead of
                                      front teeth, both features designed for ripping and tearing prickly vege-
                                      tation.  It has a long dark prehensile tongue about 45 cm in length it us-
                                      es to ‘pick’ tasty foliage and fruit from braches.

                                            Giraffes are generally sociable animals, with females living in non-
                                      territorial  herds  of  related  females  and  males  living  in  non-territorial
                                      herds  of  unrelated  males.  However,  in  the  mating  season  a  male  be-
                                      comes  very  aggressive  using  his  long  neck  as  a  weapon,  known  as
                                      ‘necking’,  to  guard  his  herd  of  females  from  any  challenger.    In
                                      ‘necking’, two males will slam their necks together in an attempt to beat
                                      the  other  into  submission.  A  ‘necking’  fight  can  last  for  about  thirty
                                      minutes or when one of the males can no longer continue. Normally, no
                                      serious injury is inflicted in these fights, but occasionally they will end
                                      in serious injury from cracked sculls or broken necks and on rare occa-
                                      sions death.

                                            As  herbivores  giraffes  prefer  to  inhabit  areas  rich  in  their  pre-
                                      ferred food, acacia, mimosa, and wild apricot trees and shrubs, normal-
                                      ly  found  in  African  savannahs  and  open  woodlands.  A  giraffe  eats
                                      around 34 kg of vegetation per day and is known, when food is scarce,
                                      to chew on large tree branches and even old bones. They spend most of
                      the day browsing and searching for food. At night they sleep fitfully for around 4 to 5
                      hours usually lying down, but some older animals seem to prefer to sleep standing-up.
                      Adult giraffes do not have many predators willing to attack them head on, possibly be-
                      cause of their size and the fact that they can run at an incredible 50 km/h. The giraffe’s
                      main predators, lions, leopards and spotted hyenas will often prey more readily on ju-
                      veniles and will usually try separating the parent from the child before they attack.
