Hippos eat mostly grass, and are classified as herbivores.
A hippo’s specialized eyes and nose, located on the top of its head, help it stay almost entirely submerged for large portions of the day.
Young hippos actually have a specialized tongue that lets them dive down and nurse while under water.
That said, during the night these heavy, often aggressive beasts come sauntering out of the water to feed.
In a line, they march out into the grasses, sometimes five miles, to fill their large bellies.
They come back to the water in a traversing loop and repeat this pattem throughout the night.
