As seen in the latest issue of World of Animals, take a look at the anatomy of a black rhino. Roll your mouse over each part to reveal the information.
Black rhinos have short skulls compared to white rhinos, and a more obvious forehead ridge.
The massive heart of a black rhino beats 30 to 40 times every minute.
Black rhinos are some of the heaviest living land animals, but their legs are surprisingly spindly. They are more athletic than elephants and can gallop, and even jump.
Rhinos are odd-toed ungulates of the same family as horses and tapirs. They have just three toes to support their immense body weight. A large pad of fat helps spread the load.
Black rhinos use their tails to fling dung across the landscape, marking their territory.
Rhinos have one stomach and rely on bacteria to ferment their food in the first part of the large intestine to extract maximum nutritional value.
One of the most obvious features that divided black and white rhinos is the top lip. It is hooked and mobile, able to grasp at stems like the end of an elephant's trunk.
The skin of a black rhino is three times thicker than expected for an animal of its size. It is made from thick keratin and, like bone, contains calcium for strength.
The horn is made from tightly packed keratin fibres, and continues to grow, like fingernails, throughout the rhino's life.
Rhinos have three toes on each foot, each ending in a tough nail. In between, a large fat pad helps to spread the load, and as the rhino steps most of the pressure is on the inside of the foot
