The video shows a manatee swimming in the water. The manatee is a large, gray animal with a rounded body and a flat tail. It has two small flippers on its sides and a long, flat snout. The manatee is swimming slowly and gracefully, moving its flippers to propel itself through the water. The background is a blurred view of the ocean floor, with rocks and plants visible in the distance. The water is clear, and the lighting is natural, suggesting that the video was taken during the day.
