Why does a hippo's nose, eyes and ears all grow on its head?
Hippos naturally like to stay in the water, and only wait until the dead of night will they go ashore for food. During the day, when it completely hides itself in the water, as long as its head is slightly exposed, its sensory organs are above the water. In this way, hippos can not only hide themselves by this means, but also pay attention to the outside world through their eyes and ears on the water, monitor the movement around them and breathe fresh air through their noses.
The habit of hippopotamus
Hippos are very good swimmers. When they are frightened, they usually avoid going into the water. I spend most of my time in the water every day. When I am submerged, I usually put my head out of the water to breathe every 3 or 5 minutes, but I can leave the water for about half an hour to breathe. Their skin will dry and crack if they don't drink water for a long time.
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. Sometimes I go to the fields to eat crops. When food is scarce, they also eat meat.
