In the video, a person is seen underwater wearing a snorkel mask and swimming towards a sea turtle. The turtle is swimming on the sandy ocean floor, and the person reaches out to touch it. The turtle does not seem to be bothered by the person's touch and continues to swim away. The water is clear, and the sandy ocean floor is visible in the background. The person's movements are slow and deliberate as they reach out to the turtle. The turtle's shell is brown and patterned, and its flippers move gracefully as it swims away. The person's snorkel mask is black, and they are wearing a green swimsuit.
