The gestation periods of animals shows that its length is largely a matter of the animal species’s size. So it takes a longer time for a big animal to grow a baby than for a small animal. Since rhinos are even bigger than the camel, I predicted a longer gestation period for them.

My prediction of the gestation period of a rhinoceros is around 450 days.
