The video shows a shark and a turtle swimming in the ocean. The shark is biting the turtle's neck, and the turtle is trying to escape. The shark is grey with a white underbelly, and the turtle is brown with a hard shell. The water is clear, and the sunlight is shining through, creating a beautiful underwater scene. The shark is much larger than the turtle, and it seems to be the predator in this situation. The turtle is struggling to get away, but the shark's teeth are too sharp.
