The northern giraffe (Giraffa camelopardalis), also known as three-horned giraffe, [2] is the type species of giraffe, G. camelopardalis, and is native to North Africa, although alternative taxonomic hypotheses have proposed the northern giraffe as a separate species. [3] [1]
The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
Males also usually have a single median ossicone on the frontal bone that is larger in northern animals and smaller in southern giraffes. [3] Giraffes can also have small additional paired occipital ossicones on the occipital bones, paired orbital ossicones associated with eyes, and azygous ossicones. [3]

Wild populations are silently slipping into extinction, with 40% of the wild giraffe population lost in just the last 3 decades,” the founder of Bright’s Zoo, Tony Bright, said in the release.
The name "giraffe" has its earliest known origins in the Arabic word zirāfah (زِرَافَةْ), of an ultimately unclear Sub-Saharan African language origin. [2] The Middle English and early Modern English spellings, jarraf and ziraph, derive from the Arabic form-based Spanish and Portuguese girafa. [3]
Rhinoceros horns, unlike those of other horned mammals, consist only of keratin. These horns rest on the nasal ridge of the animal's skull. Antlers are unique to cervids and found mostly on males: the only cervid females with antlers are caribou and reindeer, whose antlers are normally smaller than males'.
Giraffomorpha is a clade of pecoran ruminants containing the superfamilies Palaeomerycoidea (Palaeomerycidae) and Giraffoidea (Giraffidae, Prolibytheriidae and Climacoceratidae), of which the giraffe and okapi of the Giraffidae are the only extant members of the once-diverse clade as a result of a decline in diversity after the Miocene as a result of declines in temperatures.
