Giraffe
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 were thought to be one species, '' Giraffa camelopardalis'', with nine subspecies. Most recently, researchers proposed dividing them into up to eight extant species due to new research into their mitochondrial and nuclear DNA, as well as morphological measurements. Seven other extinct species of ''Giraffa'' are known from the fossil record. The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its spotted coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. Its 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 and woodlands. Their food source is leaves, fru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Giraffidae
The Giraffidae are a family of ruminant artiodactyl mammals that share a 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 (one or more species of '' Giraffa'', depending on taxonomic interpretation) and the okapi (the only known species of '' Okapia''). Both are confined to sub-Saharan Africa: the giraffe to the open savannas, and the okapi to the dense rainforest of the Congo. The two genera look very different on first sight, but share a number of common features, including a long, dark-coloured tongue, lobed canine teeth, and horns covered in skin, called ossicones. Taxonomy Evolutionary background The giraffids are ruminants of the clade Pecora. Other extant pecorans are the families Antilocapridae (pronghorns), Cervidae (deer), Moschidae ( musk deer), and Bovidae (cattle, goats and sheep, wildebeests and allies, and antelopes).

Masai Giraffe
The Masai giraffe (''Giraffa camelopardalis tippelskirchi'' or ''Giraffa tippelskirchi''), also spelled Maasai giraffe, and sometimes called Kilimanjaro giraffe, is a subspecies or species of giraffe. It is native to East Africa. The Masai giraffe can be found in central and southern Kenya and in Tanzania. It has distinctive, irregular, jagged, star-like blotches that extend from the hooves to its head. The Masai giraffe is currently the national animal of Tanzania. Taxonomy The IUCN currently recognizes only one species of giraffe with nine subspecies The Masai giraffe was described and given the binomial name ''Giraffa tippelskirchi'' by German zoologist Paul Matschie in 1898, but current taxonomy refers to Masai giraffe as ''Giraffa camelopardalis tippelskirchi''. The Masai giraffe was named in honor of Herr von Tippelskirch, who was a member of a German scientific expedition in German East Africa to what is now northern Tanzania in 1896. Tippelskirch brought back the sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giraffa Camelopardalis
The northern giraffe (''Giraffa camelopardalis''), also known as three-horned giraffe,Linnaeus, C. (1758)The Nubian or Three-horned giraffe (''Giraffa camelopardalis'').Existing Forms of Giraffe (February 16, 1897): 14. 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. Once abundant throughout Africa since the 19th century, Northern giraffes ranged from Senegal, Mali and Nigeria from West Africa to up north in Egypt. The similar West African giraffes lived in Algeria and Morocco in ancient periods until their extinctions due to the Saharan dry climate. Giraffes collectively are considered Vulnerable to extinction by the International Union for Conservation of Nature (IUCN), with around 97,000 wild individuals alive in 2016, of which 5,195 are Northern giraffes. Taxonomy and evolution The current IUCN taxonomic scheme lists one species of gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ossicone
Ossicones are columnar or conical skin-covered bone structures on the heads of giraffes, male okapi, and some of their extinct relatives. Ossicones are distinguished from the superficially similar structures of horns and antlers by their unique development and a permanent covering of skin and fur. Structure Giraffe ossicones consist of a highly vascularized and innervated bone core covered with vascularized and innervated skin. The base of an ossicone is attached to the skull with vascularized innervated connective tissue. Ossicones are formed at late gestation, but in early development they are not bony and not fused to the skull yet. Ossicones usually fuse to the skull at sexual maturity. All male and female giraffes have a pair of parietal ossicones on the parietal bones of the skull. Males also usually have a single median ossicone on the frontal bone that is larger in northern animals and smaller in southern giraffes. Giraffes can also have small additional paired occipi ...

Okapi
The okapi (; ''Okapia johnstoni''), also known as the forest giraffe, Congolese giraffe, or zebra giraffe, is an artiodactyl mammal that is endemic to the northeast Democratic Republic of the Congo in central Africa. It is the only species in the genus ''Okapia''. Although the okapi has striped markings reminiscent of zebras, it is most closely related to the giraffe. The okapi and the giraffe are the only living members of the family Giraffidae. The okapi stands about tall at the shoulder and has a typical body length around . Its weight ranges from . It has a long neck, and large, flexible ears. Its coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs, and white ankles. Male okapis have short, distinct horn-like protuberances on their heads called ossicones, less than in length. Females possess hair whorls, and ossicones are absent. Okapis are primarily diurnal, but may be active for a few hours in darkness. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Even-toed Ungulate
The even-toed ungulates (Artiodactyla , ) are ungulates—hoofed animals—which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on an odd number of the five toes. Another difference between the two is that many other even-toed ungulates (with the exception of Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do. Cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulates, and are therefore often classified under the same taxonomic branch because a species cannot outgrow its evolutionary ancestry; some modern taxonomists combine the two under the name Cetartiodactyla , while others opt to include cetaceans in the already-existing Artiodactyla. The roughly 270 land-based even-toed ungulate species include pigs, peccaries, hippo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...
