The horns of juveniles can only be seen six weeks after birth, when black membranes covering the horns fall off. White rhinos are so called not because they are "white," but because their face is "wide" (a missed translation).Īt birth, the average weight of juveniles is 40 to 60 kg, and the head and body length is 0.50 to 0.65 m. Moreover, they have flat broad mouth for grazing. The epidermis of white rhinoceroses is 1 mm thick and their dermis is 18 mm thick, on average.
Are white rhinoceros extinct skin#
White rhinoceroses have pale gray skin which is dense, tough, and has plate-like folds. These animals have 24 teeth, with a dental formula of: incisors 0/0, canines 0/0, premolars 3/3, and molars 3/3. In addition, white rhinoceros average shoulder height is 1.71 to 2.85 m, whereas their average girth is between 2.01 and 2.20 m. The average length of tail of white rhinoceroses ranges from 0.57 to 0.77 m. The average length of their head and body, not including tail, is 3.35 to 3.77 m. The shorter horns can grow up to 550 mm in length. The recorded length of longer horns is 1660 mm in length. White rhinoceroses have relatively small eyes compared to their body size, squared-shaped lips, and a long neck with a hump. They weigh approximately 1000 to 3600 kg as adults. White rhinoceroses are one of the largest terrestrial mammals. As temperature increases, they move to shadier areas such as dense forest or mid-slopes of hills. In addition, white rhinoceroses are more commonly found near riverbanks and bottomland areas during morning hours. White rhinoceroses usually live near water sources because they generally consume water as often as twice a day. Typical habitat for white rhinocerose includes dense forests, savannas, and woodlands with grassy openings. Status survey and conservation action plan", 1999 Estes, 1991 Groves, 1972 Nowak, 1999 Skinner and Chimimba, 2006) Whereas, the southern white rhinoceroses inhabit Botswana, Namibia, Swaziland, Zimbabwe, Ivory Coast, Kenya, and Zambia.įurthermore, African governments have been preserving populations of rhinoceroses in protected areas, such as Kruger National Park of South Africa, Mlilwane Game Sanctuary of Swaziland, Murchison Falls National Park of Uganda, and Meru National Park of Kenya. Presently, northern white rhinoceroses only inhabit the Democratic Republic of the Congo.
However, the current range of these subspecies is much more restricted. Southern white rhinoceroses ( Ceratotherium simum simum) were native to all of southern Africa.
Historically, northwestern Uganda, southern Chad, south-western Sudan, the eastern part of center African Republic, and northeastern Democratic Republic of the Congo were the native places for northern white rhinoceroses ( Ceratotherium simum cottoni).
