The video shows a sea turtle swimming in the ocean. The turtle is surrounded by various types of seaweed and coral. The colors of the seaweed range from green to brown, and the coral appears to be a light yellow color. The turtle is mostly brown with some green and yellow spots on its shell. It moves slowly and gracefully through the water, occasionally brushing against the seaweed and coral. The water is clear, and the sunlight filters through, creating a beautiful underwater scene.
