The video shows a hippopotamus swimming in a river. The hippopotamus is mostly submerged in the water, with only its back and head visible above the surface. The water is calm, and the hippopotamus is moving slowly. In the background, there is a herd of elephants grazing on the grassy bank of the river. The sky is overcast, and the overall color palette of the video is muted, with greys, greens, and browns dominating the scene.
