Incredible photos of a baby hippo that was stranded by the tsunami and the tortoise that adopted him.

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 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 on December 26, 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'," ecologist Paula Kahumbu, who is in charge of Lafarge Park, told AFP.

"After it was swept 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 ecologist added. "The hippo follows the tortoise exactly the way it follows 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.

Nature is a word used in two major ways, which are inter-connected in a complex way. This complexity is due to the importance of the concept in the history of science and metaphysics, particularly in Western Civilization.

1. In modern scientific writing "nature" refers to all directly observable phenomena of the "physical" or material universe, and it is contrasted only with any other sort of existence, such as spiritual or supernatural existence. In a scientific text, the unqualified term “nature” normally means the same as “the cosmos” or “the universe”.

2. Historically, and also in casual speech, “nature” does not include all things, because it excludes the artificial or man-made. For example it generally does not include manufactured objects, and also generally does not include human interaction. In this case, the unqualified term “nature” generally means the same as “wilderness” or “the Natural environment”.

The oldest meaning, which is compatible to some extent with both of these is also still common: "nature" refers to the essential properties of any particular type of thing.
