The video shows a close-up of a rock underwater. The rock is covered in various types of seaweed and other marine plants. The colors of the plants range from green to brown, and they are of different shapes and sizes. The water surrounding the rock is clear, and there are no visible fish or other marine animals in the video. The rock itself is gray and appears to be made of limestone or a similar type of rock. The video does not show any movement, suggesting that it was taken in a calm area of the ocean.
