The image shows a large rock on the bottom of the ocean floor. The rock appears to be covered in small rocks and pebbles, and there are several smaller rocks scattered around it. On top of the rock, there is a large piece of seaweed that is partially submerged in the water. The seaweed is dark brown in color and has a rough texture. There are also a few small black worms crawling around the rock. The water is clear and the sand is a light beige color.
