The Biggest Animals Kingdom and in The World | Black Rhinoceros | The species was described by Carl Linnaeus bicornis rhinoceros on 10 Edition of Systema naturae named in 1758. The name means "double-horned Rhinoceros. Probably on the skull of a single Indian one horned rhinoceros (Rhinoceros unicornis), with a second horn is artificially added by the collector This skull is known to exist and Linnaeus also mentioned India as the origin of this kind. However, he has also called on the reports of early travelers on two rhino in Africa, and when it became clear that there is only one type of rhinoceros in India, "Rhinoceros" was used to show the bicornis African rhinoceros (Rhinoceros White has ) recognized in 1812. An adult black rhino is 132-180 cm (52-71 inches) tall at the shoulder long and 2.8, but 3.8 (9.2 to 12 feet), plus a tail of about 60 cm (24 inches). Females are smaller than males. Two horns on the skull are made of keratin with the larger front horn typically 50 cm (20 inches) long, exceptionally up to 140 cm (55 inches).

The longest known horn measured nearly black rhino 1.5 meters (4.9 feet) in length. Sometimes a third to develop smaller horn. These horns are for defense, intimidation and dig roots and breaking branches during feeding. The black rhino is smaller than the White Rhino, and has a prehensile upper lip and sharp, which it uses to grasp leaves and twigs when feeding The white rhino has a square lips used to eat grass. The black rhino and the white rhino is smaller in size skull, ears, and the position of the head, which is higher than the white rhino is distinguished, is black rhino as a browser, not a grazer. The key differentiation is confirmed by the shape of the two types of mouth (lips): rhino "square" white lips is an adaptation for grazing and the rhinoceros 'hooked' black lip is adapted to facilitate navigation.

Their thick skin protects the rhino from thorns and sharp grasses. black rhinos have poor eyesight, rely more on hearing and smell. An excellent sense of smell rhino alarm the presence of predators. Like many other elements of the fauna of large mammals in Africa, the black rhino was probably now a wider range in the northern part of the continent in prehistoric times as. Petroglyphs in the Eastern Desert of Egypt southeastern show relatively convincing appearance of black rhinos in these regions in prehistoric times. In West Africa, there was plenty in a region. The black rhino has been successfully introduced in Malawi since 1993, where he died in 1990. Men are not as social as women, although sometimes order that the presence of other rhinos. They are not very territorial and often intersect other rhino territories. The ranges vary according to season and availability of food and water.

The black rhino has borne a reputation as a very aggressive and easily perceived threats. Black Rhinos fighting each other, and have recorded the highest rates of mortal combat for any mammal: about 50% of men and 30% of women die in combat-related injuries. Rhinoceros adults usually have. No natural predators due to their size and thick skin and horns death However, blacks have adult rhinos victims crocodiles get exceptionally circumstances.Calves and very rarely, a small sub-adults can prey of lions as well as up. Black Rhinoceros follow the trail to use elephants to feed the water areas. They also use small ways, if they are available. Rhinos use several forms of communication. Due to their poor eyesight and solitary nature, scent marking is often used to identify other Black Rhinos. Urine spraying occurs on trees and bushes, around water bodies and feeding areas. Comments on these issues, feel rhinos see who.

Bitches in season mark excrement. Courtship before mating are snorting and sparring with the horns among males. Another courtship is bluff and bluster, where the rhino snort and swing its head from side to side aggressively before running away repeatedly. The mother and calf stay together for 2-3 years until the next calf is born female calves have stayed longer, forming small groups.
