The video shows a group of dolphins swimming in the ocean. The dolphins are grey in color and have a streamlined shape. They are swimming in a coordinated manner, with some dolphins leading the way and others following behind. The ocean is a deep blue color, and the water is clear, allowing for a view of the sandy bottom. There are also some green plants visible in the water. The dolphins appear to be in a natural habitat, and there is no human interference visible in the video.
