Black Rhino

An adult Black Rhinoceros stands 140–170 cm (57.9–63 inches) high at the shoulder and is 3.3-3.6 m (10.8–11.8 feet) in length.[3] An adult weighs from 800 to 1400 kg (1,760 to 3,080 lb), exceptionally to 1820 kg (4,000 lb), with the females being smaller than the males. Two horns on the skull are made of keratin with the larger front horn typically 50 cm long, exceptionally up to 140 cm. Sometimes, a third smaller horn may develop. These horns are used for defense, intimidation, and digging up roots and breaking branches during feeding. Skin color depends more on local soil conditions and the rhinoceros' wallowing behavior than anything else, so many black rhinos are typically not truly black in color. The Black Rhino is much smaller than the White Rhino, and has a pointed mouth, which they use to grasp leaves and twigs when feeding. White Rhinoceros have square lips used for eating grass. The Black Rhinoceros can also be recognized from the White Rhinoceros by its smaller skull and ears. Black Rhinoceros also do not have a distinguishing shoulder hump like the White Rhinoceros.
