Giraffid
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).

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. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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, frui ... [...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 occipita ...

Bovid
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday, an ...

Giraffa Giraffa
The southern giraffe (''Giraffa giraffa''), also known as two-horned giraffe,Lesson, R. (1842)The Southern or Two-horned giraffe (''Giraffa capensis'').Existing Forms of Giraffe (February 16, 1897): 14. is a species of giraffe native to Southern Africa. However, the IUCN currently recognizes only one species of giraffe with nine subspecies. Southern giraffes have rounded or blotched spots, some with star-like extensions on a light tan background, running down to the hooves. They range from South Africa, Angola, Namibia, Botswana, Zambia, Zimbabwe, Mozambique. Their approximate population is composed of 44,500 individuals. Giraffes as one species are considered Vulnerable to extinction by the IUCN. Taxonomy and evolution 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. Once considered a subspecies of the conglomerate ''Giraffa ...

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.

Australia Zoo Giraffe-2 (17998331829)
Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. With an area of , Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical rainforests in the north-east, and mountain ranges in the south-east. The ancestors of Aboriginal Australians began arriving from south east Asia approximately 65,000 years ago, during the last ice age.written history commenced with the European maritime exploration of Australia. The Dutch navigator Willem Janszoon was the first known European to reach Australia, in 1606. In 1770, the British explorer James Cook mapped and claimed the east coast of Australia ...
