The video shows a large underwater cave with stalactites hanging from the ceiling. The cave is illuminated by a light source, and two scuba divers are swimming around the cave. The divers are wearing scuba gear and are exploring the cave. The water is clear, and the cave walls are visible in the background. The stalactites are long and thin, and they hang down from the ceiling in a curved shape. The divers are moving slowly and carefully through the water, and they appear to be taking in the sights of the cave.
