a hippopotamus is a mammal that can live in water or on land.The hippopotamus we see is often in the water, in fact, they do have a long period of time to stay in the water, the water is their main food, they will look for some water plants as their food in the water.In addition, when hippos are frightened, they will instinctively avoid the water until the danger comes back.However, hippos are not completely aquatic, which means that they do not stay in the water all the time, their swimming ability is not strong, and they can not breathe in the water.
Hippos also live on land, for example, they may come to land at night, many times they will find places rich in plants along familiar paths.But in general, hippos spend more time in the water, and they can't stay on land for too long, their skin may be dry and cracked due to lack of water.
As mentioned above, a hippopotamus stays in the water for a long time.They can not only eat in the water, but also rest in the water.But hippos are not completely aquatic animals, because they can not dive into the water for a long time, but need to breathe regularly.Their respiratory organs are lungs, so they can't breathe in water.Generally speaking, hippos will stick their heads out of the water every 3-5 minutes to breathe, and then dive into the water.They can last up to half an hour or so, after which they must come out of the water to breathe.Of course, they may also keep their heads above the surface of the water and hide their bodies in the water.
