Anabaena or Filamentous Cyanobacteria

I am passionate about many things, and Microbiology is most definitely one of them. There is something fascinating about the world that exists right in front of us, but we are not quite able to see. Me being a passionate Nerd / Geek (not a bad thing) I actually have a microscope at home, and most recently I got an adapter to connect the Microscope to my Nikon D5300 DSLR so I am not able to try and start to capture the world I can’t quite see.

I made a short trip to a nearby creek, and on the advice of some I collected some scraping from the rocks where the water passed, this was fairly slimy and filamentous and what resulted under the microscope is shown below.

I suspect this is most likely a filamentous cyanobacteria probably of the genus Anabaena but I could be wrong, if you think I am please don’t hesitate to let me know and I will update it ASAP.

I am torn between images 1 and 3.
