A Hippopotamus at the Auckland Zoo in Auckland on the North Island of New Zealand opens its mouth wide - usually a sign that the animal feels threatened.
Hippos are generally herbivores with a variety of grasses making up the majority of their diet although they have been known to eat carrion. They are a vulnerable native animal of Africa which is commonly found in zoos around the world.
The Hippo is actually the third largest mammal living on land, although many people wouldn't believe that as they are often seen in the water just lazing about or cooling themselves off in the mud. It is also surprising to learn that they can easily outrun a human on land, despite their incredibly short legs, and it has been said that you should never get between a Hippo and water as it will kill you. ... continue below the picture...
... Hippos kill more people than many other animals, such as lions or bears, and they are considered the most aggressive animal in the whole of Africa.
Today Hippos are still hunted and poached for their meat and hides and are listed as a vulnerable species. The area of the world where they have declined the most rapidly is in the Congo, due to the disruption and fighting that is going on in that region.
The Hippopotamus is an amazing animal and has been on this earth for millions of years; conservation in zoos is even more important avoid allowing them to become extinct.
