Rhinoceroses (Rhinocerotidae) are large ungulate mammals that live wild in Africa and Asia. The rhinoceros family includes five living species: the giant rhinoceros, the bush rhinoceros, the Sumatran rhinoceros, the Indian rhinoceros and the Javan rhinoceros. Four of these are endangered. Rhinos have a shoulder height of 150–185 centimeters, a body length of 420 centimeters, a tail of 50–70 centimeters. A rhinoceros can weigh up to 1,800–3,600 kilograms. Males are larger than females. Rhinoceroses are the largest land mammals after elephants. A characteristic feature of rhinoceroses is the horn in their snout. The scientific name of the tribe Rhinocerotidae comes from the Greek words rhino (snout) and keras (horn). Today, the biggest threat to rhinos is poaching for their horns. Rhinos have poor eyesight: they cannot see a person more than 30 meters away. Instead, their sense of hearing and smell are very precise. Animals like rhinos appeared on Earth for the first time in the Eocene period. Among them, Indricotherium, which lived in the Miocene period, weighed 15 tons and is the largest mammal that ever lived on earth. In the Pliocene period, rhinoceroses became extinct in North America and in the Pleistocene period in Europe and North Asia. The most famous of the ancient rhinoceroses is probably the woolly rhinoceros that lived during the last ice age, whose remains have been found preserved in permafrost.
