The giraffe is a large African hoofed mammal belonging to the genus Giraffa.It is the tallest living terrestrial animal and the largest ruminant on Earth.Traditionally, giraffes have been thought of as one species, Giraffa camelopardalis, with nine subspecies.
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).
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.
Trachelophorus is a genus of weevils in the leaf-rolling weevil family Attelabidae. Several species are known as giraffe weevils because of their elongated "necks". The best known species is Trachelophorus giraffa. Species include: [1] Trachelophorus abdominalis; Trachelophorus ardea; Trachelophorus ater; Trachelophorus camelus; Trachelophorus ...
The IUCN currently recognizes only one species of giraffe with nine subspecies. [1] Giraffa camelopardalis rothschildi is named after the Tring Museum's founder, Walter Rothschild, [2] and is also known as the Baringo giraffe, after the Lake Baringo area of Kenya, [3] or as the Ugandan giraffe.
The oldest known fossils assigned to Equidae date from the early Eocene, 54 million years ago. They had been assigned to the genus Hyracotherium, but the type species of that genus is now considered not a member of this family, but the other species have been split off into different genera. These early Equidae were fox-sized animals with three ...
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]
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 ...
