The Elusive Okapi Okapia johnstoni by Gordy Slack Deep amid the tropical swamps of the Ituri Forest live some of the few remaining wild populations of the mysterious okapi. This gentle herbivore is the giraffe's closest modern relative. It was only discovered by scientists less than a decade before the launch of the Congo Expedition.
Its spots may be found below the hocks and the insides of the legs.
A median lump is present in males. Inall alleged G. Nubian giraffe including Rothschild's giraffe G. Its range includes parts of Uganda and Kenya. The dark spots may also have paler radiating lines or streaks within them. Spotting does not often reach below the hocks and almost never to the hooves.
This ecotype may also develop five "horns". The ossicones are more erect than in other subspecies and males have well-developed median lumps. The same study found that The West African giraffe was more closely related to the Rothchild's giraffe than the Kordofan and its ancestor may have migrated from eastern to northern Africa and then to its current range with the development of the Sahara Desert.
Spots may or may not extend below the hocks, and a median lump is present in males.
The spotting pattern extends throughout the legs but not the upper part of the face. The neck and rump patches tend to be fairly small. The species also has a white ear patch. The spots extend down the legs and get smaller.
The median lump of males is less developed. A median lump is usually present in males. The median lump of males is underdeveloped.
The tongue, and inside of the mouth are covered in papillae.
Male giraffes become darker as they age. At least 11 main aromatic chemicals are in the fur, although indole and 3-methylindole are responsible for most of the smell. Because the males have a stronger odour than the females, the odour may also have sexual function.
The radius and ulna of the front legs are articulated by the carpuswhich, while structurally equivalent to the human wrist, functions as a knee. The giraffe's pelvis, though relatively short, has an ilium that is outspread at the upper ends.
Walking is done by moving the legs on one side of the body at the same time, then doing the same on the other side. To get back up, it first gets on its knees and spreads its hind legs to raise its hindquarters. It then straightens its front legs.
With each step, the animal swings its head.

The Okapi was not discovered by the Western world until the end of 19th century. Okapis are very elusive and shy creatures that are rarely seen by people. Giraffes have taught generations of students how evolution works. Not directly, of course.
Communicating through nocturnal humming is a barrier to classroom instruction. But the modern giraffe. May 17, · Genetic analysis finds some clues. because the giraffe only separated from a common ancestor with its closest relative, the okapi, around 11 million years ago.
In that time, the giraffe . Most notably, the sixth vertebra showed a ridge on its surface like an okapi, but not the giraffe. Detailed anatomical analysis suggested that Samotherium is not an ancestor of the giraffes, but a close relative .
