YOU, the Harpo Marx image master of FR, actually wrote something?!!!

These are some of the most interesting creatures on Earth. . . and they do some very WEIRD behaviors. We've seen them all swimming in the same direction in a coordinated motion, in time, within the field of the microscope;s viewfinder. Once we saw what we thought was the Jolly Green Giant of Spirochetes. . . it extended from one side of the field of view to the other and acted in a coordinated manner. Then after about ten minutes, it suddenly disconnected and became SIX discrete spirochetes that all went their separate ways. Other times we see them suddenly decide to form a big puff ball of spirochetes, with one end into the center, and tails (?) out, sometimes comprising dozens to up to a hundred spirochetes. If they are threatened, the curl into a ball for the duration and can dry out until conditions are better, sometimes for years. They can survive even attacks of antibiotics this way.
