A baby hippopotamus that survived the tsunami waves on the Kenyan coast has formed a strong bond with a giant male century-old tortoise in an animal facility in the port city of Mombassa, officials said The hippopotamus, nicknamed Owen and weighing about 300 kilograms (650 pounds), was swept down Sabaki River into the Indian Ocean, then forced back to shore when tsunami waves struck the Kenyan coast, before wildlife rangers rescued him. It is incredible. A-less-than-a-year-old hippo has adopted a male tortoise, about a century old, and the tortoise seems to be very happy with being a ‘mother’. After it was swept away and lost its mother, the hippo was traumatized. It had to look for something to be a surrogate mother. Fortunately , it landed on the tortoise and established a strong bond. They swim, eat and sleep together. The hippo follows the tortoise exactly the way it followed its mother. If somebody approaches the tortoise, the hippo becomes aggressive, as if protecting its biological mother. See a lot more cute pictures on this website.
