T<\/span>he eastern black rhinoceros is a three-toed mammal with a beaklike upper lip, and thick, plate-like skin around the shoulders, haunches, and parts of the head. The powerfully built animal has two horns on its head, with the front thinner and longer. The horns grow throughout the rhino\u2019s lifetime and are used for diverse purposes including display, greeting, and defence. Despite the animal\u2019s name, the black rhino\u2019s skin is grey. Black rhinos are among the world\u2019s largest land animals, measuring up to 3.75 metres from head to base of tail, and weighing up to 1,400 kilogrammes. Females are smaller than males.<\/p>\n<\/div>
