Hippopotamus

The hippopotamus is a large semi-aquatic mammal that lives in sub-Saharan Africa.
It prefers habitats with shallow water and abundant grassland, where it can submerge itself during the day and graze at night.
The hippopotamus is also known as the river horse, because it spends most of its time in rivers, lakes, and swamps.
The hippopotamus is one of the heaviest land animals, weighing up to 8,000 pounds.
It is also one of the most aggressive and unpredictable animals, especially when defending its territory or young.
The hippopotamus is classified as vulnerable by the IUCN, due to habitat loss, poaching, and human-wildlife conflict.
