The video shows a large lizard with a scaly body and a long tail. The lizard is eating a fish that is lying on a wooden surface. The lizard's mouth is open, and it is biting and chewing on the fish. The fish appears to be dead, with its mouth open and eyes closed. The lizard's skin is a dark brown color, and it has a rough texture. The wooden surface has some dirt and debris on it. There is a fence visible in the background, suggesting that the lizard is in an enclosure.
