The video shows a group of dolphins swimming in the ocean. The water is a deep blue color, and the dolphins are gray with white underbellies. They are swimming in a pod, with some dolphins swimming in the foreground and others in the background. The camera follows the dolphins as they move through the water, occasionally coming close to the camera. There is also a person in a wetsuit and snorkel mask swimming alongside the dolphins. The person is wearing a black wetsuit and has a yellow snorkel mask. The dolphins and the person are moving in the same direction, and the person seems to be observing the dolphins.
