Ok here's the situation I was looking in my frog tank and I saw thease little moving specks in the aquatic moss. So I got out my electron microscope and started studying them closly. I created small enclosures in test tubes, beakers, and flasks to contain thease organisms. At first glance I thaught they were water fleas but after examining them more closely I quickly found out that they defenently aren't water fleas they look like microscopic tadpoles with wiscers and very fine hairs along their bodies. Their tails are compleatly transparent with what look like smaller moving organisms inside. So after a long day of reserch and Internet searches to find out what they are I have hade absolutly no luck identifying them so I thaught I would ask you all and maby you will have more luck than I did at finding out what thease things are. Here's my only picture I was able to get sorry it didn't come out very well but it wouldn't stay still on the microscope slide.
