The video shows a large body of water with a brownish color, possibly due to mud or sediment. In the water, there is a large animal with a long neck and back, which could be a dinosaur or a similar creature. The animal is moving slowly through the water, occasionally submerging its head and back. The water is moving rapidly, indicating a strong current or waves. The animal's movements are slow and deliberate, and it seems to be navigating through the water with ease.
