The video shows a scene from the animated movie Finding Nemo. It features two clownfish, Nemo and his father, Marlin, swimming in the ocean. They are seen hiding inside a sea anemone, which is a type of coral that lives in the ocean. The sea anemone is pink and has long tentacles that move with the water. The clownfish are orange with white stripes and have big eyes. They swim in and out of the anemone, sometimes hiding and sometimes coming out to look around. The background shows a blue ocean with other fish and coral in the distance.
