The giraffe is a protected species in most of its range. It is the national animal of Tanzania, [ 140 ] and is protected by law, [ 141 ] and unauthorised killing can result in imprisonment. [ 142 ] The UN-backed Convention of Migratory Species selected giraffes for protection in 2017. [ 143 ]
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).
Living giraffes were originally classified as one species by Carl Linnaeus in 1758, under the binomial name Cervus camelopardalis. Morten Thrane Brünnich classified the genus Giraffa in 1772. [ 6 ] Once considered a subspecies of the conglomerate Giraffa camelopardalis species, recent studies proposed the southern giraffe as a separate species ...
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.
The current IUCN taxonomic scheme lists one species of giraffe with the name G. camelopardalis and nine subspecies. [1] [7] A 2021 whole genome sequencing study suggests the northern giraffe as a separate species, and postulates the existence of three distinct subspecies, [8] and more recently, one extinct subspecies. [9] [10] [11]
The third ossicone can often be seen in the center of the giraffe's forehead, and the other two are behind each ear. Regarding the hybridization and habitat of the species: Rothschild’s giraffes have different genetic markers that other species usually do not, which keeps their populations safe from extinction and hybridization overlap.
Giraffe ossicones consist of a highly vascularized and innervated bone core covered with similarly vascularized and innervated skin. [1] They are attached to the skull with vascularized, innervated connective tissue. [1] Ossicones are formed at late gestation, but in early development they are not bony and not fused to the skull yet.
Sivatherium ("Shiva's beast", from Shiva and therium, Latinized form of Ancient Greek θηρίον - thēríon) is an extinct genus of giraffid that ranged throughout Africa and Eurasia. The species Sivatherium giganteum is, by weight, one of the largest giraffids known, and also one of the largest ruminants of all time. [3]
