The video shows a close-up view of a body of water with several small, elongated creatures swimming around. These creatures have a translucent body with a purple hue and are moving in different directions. The water appears to be slightly murky with small particles floating around. There are also some yellow and green objects visible in the water, which could be algae or other organic matter. The creatures are the main focus of the video, and their movements are the primary action observed.
