The male rhinoceros matures around 7-8 years and the females at 5-6 years old. Mating is preceded by courtship behaviour that includes snorting and sparring with the horns. Mating is repeated several times during a period of 2 to 3 days and may last about 30 minutes each time. Male rhinos have no scrotum, as the testes are internal.
Number of Young
One calf.
Gestation
17-18 months.
Birth
A single calf is born weighing around 35-55 kilograms. It follows its mother around after birth, staying with her only until the next calf is born when it is then driven off to find its own territory.
