1. Find a Urocentrum turbo that is spinning like a top (and bobbing up and down, to-and-fro)
2. Get curious about that little tuft at the rear of the cell
3. Put on a 100X and oil the slide
4. Try to take a picture

Despite the low percentage of in focus shots, there were few images that were interesting. Urocentrum use an extremely thin, "invisible" tether at the rear of the cell to remain in approximately the same area as the feed. Occasionally they will break free and move to a new location. This is why I wanted a better look at that rear tuft of cilia. The actual tether can't be seen, but it appears the rear cilia become twisted as the cell spins. In three of the shots the mouth, which is located near the center of the cell, can also be seen.
