Here's a breakdown:
Africa:
* Black rhinoceros: Found in southern and eastern Africa, specifically in countries like Kenya, Tanzania, Namibia, and South Africa.
* White rhinoceros: Mainly found in South Africa, with smaller populations in Namibia and Zimbabwe.
Asia:
* Greater one-horned rhinoceros: Primarily found in India's Assam region and parts of Nepal.
* Sumatran rhinoceros: Found only on the Indonesian island of Sumatra.
* Javan rhinoceros: Only found on the island of Java in Indonesia, with a very small population.
It's important to note that rhino populations are critically endangered, and their habitats are shrinking due to poaching and habitat loss.
