The video shows a close-up of a large fish swimming in the water. The fish has a long, slender body with a pointed snout and a red mouth. The water is murky, and the fish is the only visible creature in the frame. The fish moves slowly and gracefully, with its fins gently propelling it forward. There is a text overlay on the video that reads "ZITTERAAL," which translates to "shivering" in English.
