  Hi!
  Thanks for question! There are 2 main popular ways to swim, which you find for swimming bacteria but also for big animals or humans: First, you can perform something like a breast-stroke, which humans also do with their arms, and some tiny organisms also do with 2 attached appendages (see for example this https://www.youtube.com/watch?v=0xo77Q09Brc). Second, many bacteria have appendages at the back of their body, and when they rotate them they can move forward – like a corkscrew motion.
