Photosynthetic eukaryotes other than plants
This single Closterium was found in my tiny garden pond (<1 square metre) today, and put under my microscope. It would be great if I could have some identification help, as I know some people are experts at these micro algae (like Dr Denton).
It is 182 x 25 microns.
Finally got myself a microscope, and a new universe awaits...
