Black rhinos

It is critically endangered, with very few left in the wild, and a dwindling population in captivity. Introduction Like many other rhino species, human poachers have decimated these creatures to a mere fraction of the original population. The western subspecies of black rhino was declared officially extinct in

Edit The intraspecific variation in the black rhinoceros has been discussed by various authors and is not finally settled. It became extinct due to excessive hunting and habitat destruction around Relict populations in northern Somalia vanished during the early 20th century.

Nearly extinct, possibly only one surviving specimen in Botswana. Black rhinos are considered extinct across most of this area and its conservational status is unclear. Probably surviving in Kenyan reserves. The evidence from Liberia and Burkina Faso mainly rests upon the existence of indigenous names for the rhinoceros.

In an intensive survey across its putative range in Cameroon failed to locate any, leading to fears that it was extinct in the wild. Today, its range is limited primarily to Tanzania. Between four and five million years ago, the black rhinoceros diverged from the white rhinoceros.

The females are smaller than the males. The longest known black rhinoceros horn measured nearly 1. Sometimes, a third, smaller horn may develop. These horns are used for defense, intimidation, and digging up roots and breaking branches during feeding.

It has a pointed and prehensile upper lip, which it uses to grasp leaves and twigs when feeding. The white rhinoceros has square lips used for eating grass.

The black rhinoceros can also be distinguished from the white rhinoceros by its size, smaller skull, and ears; and by the position of the head, which is held higher than the white rhinoceros, since the black rhinoceros is a browser and not a grazer.

Black rhinos have poor eyesight, relying more on hearing and smell. Their ears have a relatively wide rotational range to detect sounds.

Prehistorical range Edit As with many other components of the African large mammal fauna, black rhinos probably had a wider range in the northern part of the continent in prehistoric times than today. However this seems to have not been as extensive as that of the white rhino.

Its occurrence further to the west is questionable, though often purported to in literature. The remaining populations are highly scattered.

Some specimens have been relocated from their habitat to better protected locations, sometimes across national frontiers. Behaviour Black rhinoceros are generally thought to be solitary, with the only strong bond between a mother and her calf.

In addition, males and females have a consort relationship during mating, also subadults and young adults frequently form loose associations with older individuals of either sex.

Home ranges vary depending on season and the availability of food and water. Generally they have smaller home ranges and larger density in habitats that have plenty of food and water available, and vice versa if resources are not readily available.

Sex and age of an individual black rhino influence home range and size, with ranges of females larger than those of males, especially when accompanied by a calf. Black rhinos have also been observed to have a certain area they tend to visit and rest frequently called "houses" which are usually on a high ground level.

These "home" ranges can vary from 2. Black rhinoceros in captivity and reservations sleep patterns have been recently studied to show that males sleep longer on average than females by nearly double the time. Other factors that play a role in their sleeping patterns is the location of where they decide to sleep.

Although they do not sleep any longer in captivity, they do sleep at different times due to their location in captivity, or section of the park.

The black rhino has a reputation for being extremely aggressive, and charges readily at perceived threats. They have even been observed to charge tree trunks and termite mounds. Black rhinos will fight each other, and they have the highest rates of mortal combat recorded for any mammal: Adult rhinos normally have no natural predators, thanks to their imposing size as well as their thick skin and deadly horns.

Black rhinoceros follow the same trails that elephants use to get from foraging areas to water holes. The optimum habitat seems to be one consisting of thick scrub and bushland, often with some woodland, which supports the highest densities.

Their diet can reduce the amount of woody plants, which may benefit grazers who focus on leaves and stems of grassbut not competing browsers who focus on leaves, stems of trees, shrubs or herbs.The black rhinoceros was once widespread south of the Sahara.

Now, fewer than 2, remain. It has been hunted almost to extinction for its horns, which are prized in China and the Middle East. For one horn, a poacher can earn twice what he would earn in a year as a farmer. The black rhino is. Black Rhino Wheels was developed with two types of vehicles in mind, The first being aggressive fitments with negative offset that works well with lifted applications.

The black rhinoceros or hook-lipped rhinoceros (Diceros bicornis) is a species of rhinoceros, native to eastern and southern Africa including Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe.
