NAIROBI (AFP) - 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 650 pounds, was swept down the
Sabaki River into the Indian Ocean, then forced back to shore when the tsunami waves struck the Kenyan Coast on December 26, before Wildlife Rangers rescued him.

" It is encredible. 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 its 'mother', Ecologist Paula Kahumbu, who is in charge of Lafarge Park, told AFP.

"After it was swept away and lost it's 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 Ecologist added. "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," Kahumbu added. "The Hippo is a young baby, he was left at a very tender age and by nature, Hippos are social animals that like to stay with their mothers for four years," he explained.
