Despite being aggressive animals, the female [[hippopotamus]] is very nurturing and sensitive when caring for offspring.<ref name=":2">{{Cite web|title=Hippopotamus Reproduction|url=http://www.hippoworlds.com/hippopotamus-reproduction/|website=Hippoworlds|trans-title=Reproduksi Kuda Nil|access-date=16 Mei 2016}}</ref> Mating and birth both occur in the water for hippopotamus. This is because it gives them privacy when conceiving and helps conserve energy during birth. The female hippo normally averages around 5–6 years, while males are average an age of 7–8.<ref name=":2" /> During mating season the male hippopotamus will find a mate out of the herd, showing interest by smelling the female's posterior end.<ref name=":3">{{Cite web|title=Hippopotamus amphibius (hippopotamus)|url=http://animaldiversity.org/accounts/Hippopotamus_amphibius/|website=Animal Diversity Web|access-date=16 Mei 2016}}</ref> As long as the male acts submissive during courting season, the adults in the herd will not interfere. Once the male finds the female he wants to mate with, he begins provoking the female. He then will push the female into the water and mount her. In order to alert the herd or other animals that may be lurking around, the male will let a loud wheezing sound.<ref name=":3" /> Preceding birth, the female exhibits aggressive behavior, leaving the herd until after the birth of the calf. Although hippopotamuses can mate anytime of the year, the mating season ranges from February to August. Because the energy cost is high, the female generally only has one offspring in a two-years span.<ref name=":2" />
