The video shows a large hippopotamus in a body of water. The hippo is mostly submerged, with only its head and back visible above the water's surface. The animal is moving its head and mouth, possibly interacting with something or someone in the water. The hippo's skin appears to be a dark gray color, and its eyes are open and alert. The water around the hippo is disturbed, indicating movement. The background is not clearly visible, but it appears to be a natural setting, possibly a river or lake.
