Notes

The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal, the tallest living terrestrial animal and the largest ruminant. Its species name refers to its camel-like shape and its leopard-like colouring. Its chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. The nine subspecies are distinguished by their coat patterns.

The giraffe's scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannahs, grasslands, and open woodlands. Their primary food source is acacia leaves, which they browse at heights most other herbivores cannot reach. Giraffes are preyed on by lions; their young are also targeted by leopards, spotted hyenas, and African wild dogs. Giraffe are gregarious and may gather in large aggregations. Males establish social hierarchies through "necking", which are combat bouts where the neck is used as a weapon. Dominant males gain mating access to females, which bear the sole responsibility for raising the young.

The giraffe has intrigued various cultures, both ancient and modern, for its peculiar appearance, and has often been featured in paintings, books, and cartoons. It is classified by the International Union for Conservation of Nature as Least Concern, but has been extirpated from many parts of its former range, and three subspecies are classified as Endangered. Nevertheless, giraffes are still found in numerous national parks and game reserves.The giraffe belongs to the suborder Ruminantia. Many ruminants have been described from the mid-Eocene in Central Asia, Southeast Asia, and North America. The ecological conditions during this period may have facilitated their rapid dispersal. The giraffe is one of only two living species of the family Giraffidae, the other being the okapi. The family was once much more extensive, with over 10 fossil genera described. Their closest known relatives are the extinct deer-like climacocerids. They, together with the family Antilocapridae (whose only extant species is the pronghorn), belong to the superfamily Giraffoidea. These animals may have evolved from the extinct family Palaeomerycidae which might also have been the ancestor of deer. There's up to nine subspecies of giraffe are recognised (with population estimates as of 2010): Giraffes can be found in central, eastern and southern Africa. Giraffes live at the savannas of Africa, where they roam freely among the tall trees, arid land, dense forests and open plains.
