Okapi (Okapia johnstoni) – the African unicorn
Okapi – a mysterious animal living in the Ituri tropical rainforests in the Democratic Republic of the Congo in Central Africa. It is the most closely related to the giraffe, but resembles a zebra. Because it’s very cautious, and, thus, difficult to capture, it has been called the African unicorn for many years. Few people genuinely believed that it had existed…
- Class: Mammalia
- Order: Artiodactyla
- Family: Giraffidae
- Genus: Okapia
- Species: Okapia johnstoni
The okapi occurs only on a small jungle territory in Central Africa. It inhabits the Ituri forests in the northeast of the Democratic Republic of the Congo.
The okapi prefers the altitudes ranging from 500 to 1000 meters above the sea level the most. However, it can be sometimes found in higher areas, especially in mountainous eastern parts of rainforests.
Because of a very high level of precipitation in the areas of distribution, the okapi’s coat is very oily so that it doesn’t absorbs water. Therefore, the coat is beautifully silky and shiny.
The range of distribution is bordered by natural conditions: mountains in the east, swamps in the southern-east, muddy forests in the west, and savannah in the north.
The okapi can be found primarily in the Epul and Wamba areas, and in the Okapi Wildlife Reserve (French: Parc National de la Ocapi) in the Ituri Forest (French: La forêt équatoriale de l’Ituri).
The history of the okapi is quite amazing and deserves some attention. Although this animal was probably well-known to ancient Egyptians, which can be proved by drawings of the okapi from that period, Europeans discovered the okapi only in 1901.
For many years, people from Europe who had come to Africa heard about a mysterious animal, but they had never seen it. Therefore, the okapi was called the African unicorn.
Only a British governor of Uganda – sir Henry Johnston – managed to document the existence of the okapi. It was possible thanks to the goodwill of natives who showed him traces of this animal. The man was able to obtain pieces of the animal’s skin and its skull. On its basis, the okapi was correctly classed to the relatives of the giraffe.
The okapi has a reddish, dark back. Horizontal stripes on their fore and hind legs are their characteristic feature which makes them resemble a zebra from a distance. Such coloration helps the young follow their mother through a dense rainforest, but also serves as camouflage.
Similarly to giraffes, okapis have long legs and a robust body, but their necks are definitely shorter.
What differentiates the okapi from other animals is its uniquely long, bluish-gray tongue, that can be even 35 cm (14 in) long. This enables the animal to clean its eyelids and ears with it – both inside and outside. Males have short bumps covered with skin that resemble horns on their heads, called ossicones. Big ears and great hearing helps the okapi detect a predator from a distance.
The okapi is herbivorous, so it feeds on leaves, buds, grass, ferns, fruit and fungi.
Many plants eaten by the okapi are poisonous for human.
Okapis pair only during the mating season. Their mating behaviors include licking and rubbing on each other.
Gestation lasts about 14-15 months (420-450 days), and only one calf is born – always during the wet season. The calf weighs about 16 kg (35 lb) and stands to 80 cm (31 in) tall at the shoulder.
The young okapi leaves its birth place after two months. Only then, it is ready to escape a predator. The okapi’s lifespan is about 15 years.
The okapi is considered to be diurnal, but photos taken recently may deny such a thesis. An individual that was eating leaves at 2.33 a.m. was captured in the photos – it means that the okapi can be active also at night.
However, it is certain that the okapi is solitary and socializes only in order to reproduce. The mother and her calf are the only exception. There are 0.6 animals per square kilometer (0.6 square mile) on average.
The okapi likes quiet and peace. Therefore, because of the limited home range and the development of human settlements, there is a problem with the decreasing population of the okapi.
Okapis have several ways to mark their territory. They use mostly urine and tar-like substance produced by scent glands. Males protect their territories but they let females cross them in order to get food.
Okapis in the wild
Although the okapi wasn’t classed as an endangered animal, because of its reduced habitat, the okapi population has been constantly decreasing. It is estimated that there are from 10 to 20 thousand individuals in the world.
Okapis in captivity
An okapi is certainly a unique attraction in every zoo, especially, if you take the difficulty in keeping it in captivity into account.
In 2011, there were only 155 okapis in zoos around the world. Most of them were in North American and European zoos, two individuals in the Republic of South Africa, and 7 okapis in Japan.
When they were discovered by Europeans, every zoo wanted to have them right away. However, first transport attempts failed and were associated with high level of mortality – mostly because of rigors of travel and stress. The first alive okapi arrived in Europe in 1918, so only 17 years after the discovery.
