A high key shot as the weather was very hot and it was in the middle of the day.
This hippo was submerged to keep cool but kept coming to the surface every 6-7minutes to breathe.
Hippos are the only land mammals that mate underwater. They do not mate at all on land. The babies are also born underwater but are pushed by the mother to the surface to take their first breaths.
The babies are very vulnerable whilst they are still young. The fighting males often kill them by mistake with their testosterone bulks.
