A baby hippo rescued after floods in Kenya caused by the tsunami in the Indian Ocean has befriended a 100-year-old tortoise in a zoo.
The one-year-old hippo calf, who keepers have called Owen, was found alone and dehydrated by wildlife rangers near the ocean.
He was put in a wildlife enclosure near Mombassa, and soon became pals with the tortoise, who is a similar colour.
Park officials say they sleep and eat together, and have become inseparable.
Pauline Kimoti, from the park, said: "Since Owen arrived on 27 December the tortoise behaves like a mother to it.
"The hippo follows the tortoise around and licks his face."
The tortoise is called Mzee, which is Swahili for old man.
The park plan to place Owen with Cleo, a lonely female hippo, when he gets bigger.
