Black Rhino

I think,this animal is very interesting.The rhinoceros is live eastern and central areas of Africa including Kenya, Tanzania, Cameroon, South Africa, Namibia and Zimbabwe. Although the Rhino is referred to as black, it is actually more of a grey-white colour in appearance. It will sometimes take on the colour of the soil that it lives around.In the news,an adult Black Rhinoceros stands 140 - 170 centimetres (57.9 - 63 inches) high at the shoulder and is 3.3 - 3.6 metres (10.8 - 11.8 feet) in length. An adult weights from 800 to 1400 kilograms (1,760 to 3,080 pounds), some may weight 1820 kilograms (4,000 pounds), with the females being smaller than the males. The rhinos two horns on their skull are made of keratin with the larger front horn typically 50 centimetres long, some can measure up to 140 centimetres. Sometimes, a third smaller horn may develop. These horns are used for defence, intimidation and digging up roots and breaking branches during feeding.The Black rhino is smaller than the White rhino.Black Rhinos tend to live alone. The Black Rhinos skin harbours many external parasites, which are eaten by birds.Black Rhinoceros Behaviour:Black Rhinos are heavy browsers that restrict woody plants from over-growing in their habitat. This is important because it allows grasses to grow which provides food for many other animals on the grassy plains. Black Rhinos have been known to attack trees and rocks by mistake. They rely heavily on their strong sense of smell and well developed hearing. Black Rhinos will attack other animals though if their territory is threatened, they also fight amongst themselves. Black Rhinos will fight each other over territory and females - even courting males and females sometimes fight one another. Black Rhinos use the larger of their two horns as a weapon when fighting. Sometimes it can break off, however, this regenerates and grows back eventually. Adult Black Rhinoceroses are solitary in nature, coming together only for mating. Mating does not have a seasonal pattern, however, births tend to be towards the end of the rainy season in drier environments.The gestation period of a female Black rhino is 16 months. She will give birth to one single calf. The calf will weight about 100 pounds at birth. Black rhino mothers are very affectionate towards their young and will look after them for years, protecting them and teaching them how to survive independently. Young Black rhinos will live with their mother until another sibling is born, they are about 2 years old when this happens and are almost adult size and ready to go off and live independently.
The overall life span of the Black rhino is between 25 - 40 years, in captivity they live a little longer because they are more protected - usually to about 45 years old.Okey,it’s little news of Black rhino.
