What do hippopotomus eat?

Answer 1

Hippos are herbivores and their diet consists mainly of grass and some water plants. Hippos do most of their eating during the night, while during the day hippos spend most of their time basking in the sun on a sandbar or floating lazily in the water with just their ears, eyes, and nostrils, and perhaps their back and top of the head, exposed.
