A truly weird thing!

I shot this Scyphozoan Jellyfish through the microscope after sucking him up with an eye dropper. He actually is swimming around in a drop of salt water if that is any indication of how big he is. Unfortunately I only have one objective lens in the scope and I could have done with a little wider shot, but you can get the idea of how this guy swims by watching the video.
