Arthrospira

What a beautiful bacteria, I hope its a good one.

Thank you! As a matter of fact, I am a limnologist! (I study freshwater ecosystems.) I work a lot with aquatic vascular plants and macroalgae. I have a project in Lake Wingra on filamentous algae, and while identifying specimens under the scope, I couldn't help but snap a photo of this perfect spiral cyanobacterium!

Nice first spotting on Noah - are you a biologist studying these?
