One tonne hippo lives with a couple

The video introduces Jessica, a hippo with a unique bond with humans, particularly Tony Jubera, who found her as a baby. Jessica lives freely, choosing to stay with the family despite having the option to join wild hippos. Her daily routine includes sunbathing, swimming, and enjoying snacks with the family. Jessica is seen as a family member and has never shown aggression, unlike typical hippos. She is expected to live into her 40s and may breed in the future.
