The picture shows a hippopotamus

Hippos are among the heaviest land mammals and live primarily in central and southern Africa near bodies of water.
They have very thick skin, which can be up to five centimeters thick and is covered with a reddish-brown, mucous secretion that serves as a natural sunscreen.
Their eyes, ears, and nostrils are located high on their heads, allowing the animal to almost completely submerge itself and still breathe and see.
Despite their sluggish appearance on land, hippos can be very active in the water and are classified as an endangered species
