In order to meet the needs of life in the water, hippos have almost all their eyes, nose and ears on their heads. In this way, when the hippo's stout and fat body is immersed in the water, as long as the head is slightly exposed, the five senses can be exposed to the water. Hippos can not only hide themselves, but also observe the movements around them quietly.

In addition, hippopotamus's nostrils, eyes and ears have a "cover" to prevent water from flowing in. When it swims, this wonderful waterproof "cover" will tightly cover its nostrils, eyes and ears to prevent a drop of water from entering.

The habit of hippopotamus

Hippos move in pairs or in groups, and older males often move alone. Nocturnal: they sleep or rest in the river or riverside almost all day, come out for food at night, and sometimes swim more than 30 kilometers downstream for food.

Mainly feed on aquatic plants; I occasionally eat land crops, mainly grass, and sometimes I go to the fields to eat crops. When food is scarce, they also eat meat. It is said that hippopotamus is the largest carnivore (omnivore) on the road. Hippo has not settled down: it doesn't stay in one place for a long time, but moves to a new place every few days.
