Animal experts hope the rhinos - two males and two females -

will breed in their natural habitat in Africa.

Only eight Northern White rhinos are known to survive

worldwide, all of them in captivity: six in the Czech Republic

and two in the US.

The last four living in the wild in Africa have not been seen

since 2006.

The article also says that returning these animals to their

natural habitat, they were hoping that the females would

become more fertile, and the males will be interested in the

females. So that they could continue to reproduce.

This article made known to me that, the importance of the

reproduction process for the white rhinos as the number of its

species left is very limited. Before reading the article, i thought

that they were normally producing their offspring instead of

being enclosed in the zoo, not letting them to be freely moving

around in their natural habitat.
