Hyenas or hyaenas are feliform ("cat-like") carnivorous mammals. There is four recognised spe-
      cies of Hyenas, each in its own Genus* and all members of the family Hyaenidae**. Hyenas are native
      to Africa and are one of Africa’s most common large carnivores. The size of the hyena, even within the
      same species, can vary according to the location of the animal. However, in general, the largest of the
      species is the female spotted hyena around 95 to 165.8 cm in length, and about 70 to 91.5 cm tall at the
      shoulders and weighs 67 to 75 kg. The male is slightly smaller. The smallest of the species is the Aard-
                                                                 wolves  at  around  50.8  cm  tall  and  about
                                                                 76.2cm in length and weighs around 7 to 13kg.

                                                                      spotted hyena (Crocuta crocuta)
                                                                 Genus  Hyæna
                                                                      striped hyena (Hyaena hyaena)
                                                                 Genus Parahyaena
                                                                      brown hyena (Parahyaena brunnea)
                                                                 Genus Proteles
                                                                      Aardwolf (Proteles cristata).

                                                                      Hyenas are  very distinctive  animals;  they
                                                                 have long powerful forelegs with short hindlegs,
                                                                 giving their back a sharp downward slope. Their
      **Hyaenidae                                                dog-like  paws  have  four  toes  with  blunt  non-
                                                                 retractable  claws.  They  have  a  thick  powerful
                              neck  with  a  long  to  short  hair  mane  running  from  the  head  to  the  shoulders.
                             Their head is round with a short pointed snout, with small round eyes and large
                             prominent ears. They also have a very distinctive way of communicating, like their
                             frightening,  ‘wailing  calls’,  their  ‘howling  screams’,  and  above  all,  their  loud
                             mocking type “laughter”.  Sadly, it’s their looks and sounds that have spawned
                             decades of contempt and dislike for them. In many cultures, people believe they
                             influence spirits, steal livestock, eat children and raid graves to eat the dead. Even
                             in  the  supposed,    ‘enlightened  societies’  of  today,  they  are  still  associated  with
                             witchcraft and killed for their body parts to use in rituals.

                                  Hyenas  are  found  in  most  habitats  across  Africa;  savannas,  grasslands,
                             woodlands, forest edges, sub-deserts, even living high up in mountains. They are
                             sociable animals and usually live and bring up their young in communal caves or
                             empty underground tunnels, or burrows. They live and hunt in packs or clans of
                             various sizes. For instance, the spotted hyenas may form packs of 80 or more ani-
                             mals; though, the general size is around 5 to 10 animals, especially when hunting.
                             The centre of all hyenas’ activities is the communal den where they nurture their
                             young. Their territory can range from 15 to over 100 square miles, and although
                             they do not enforce it, they do mark it out with their droppings and by depositing
                             a  pungent  liquid-like  substance  they  secrete  from  the  anal  glands  on  the  grass
                             along the boundaries.

                                  Hyenas are Africa’s top carnivorous predators. Like most wild animals, they
                             will scavenge dead animals or left over kills by others, even kills they have made
                             earlier. When a lion or other large animal makes a kill, hyenas are often unfairly
                             portrayed as skulking in the background, as though they alone are waiting to steal
                             or scavenge any leftovers. This behaviour is not unusual among wild animals, any
                             animal knowing of a kill will come and try to get in on the kill; lions are known to
                             attack and steal kills from hyenas. However, the truth is that the bulk of the hye-
                             na’s food comes from direct kills;  they will  attack and kill any animal they can
                             overcome. They are very intelligent, and when hunting in packs, they will often
                             lure or chase an animal into a prearranged trap.  After a kill, hyenas announce it
                             to other members of the pack by communicating in loud screams or chattering
                             “laughter”. Packs share the bounty, even with those not directly involved in the
                             kill.
