Hi Mitch, wonderful images of Volvox, thanks for this eye-candy. Please purchase ready mixed 1.5% methyl cellulose. It's there next to your alcohol drop-bottle, next to your optical immersion-oil bottle, in with your other microscopy kit. A 1oz bottle keeps well for a few years if you don't contamin...

Well...perhaps the larval stages (also called, nauplie) of a related 'water flea', eg., of Cyclops or 'fairey shrimp'/Artemia species? But again thanks for the hydra image. And I hope you are 'culturing the hydras' with 'water flea' feedings ? charlie guevara, NJ,US

Hello all, I've benefitted from microscopy since childhood, I'm new to this group. I'd ask if two questions I have can be given advice/replys? 1) Has anyone in this forum read of, been inspired by an active circa 1950's-60 microscopist/author/photomicroscopist: Roman Vishniack (?spelling??) ? 2) Whe...

Thanks for the images,and the biology notes, Bernhard. This late springtime thankful rainseason/past snow melt runnoff..NJ,US watersheds host explosive blooms of Spirogyra and other thalophyte algae 'subsurface streamers' in temporarywater channels in watershed highlands. Perhaps Bernhard could give...

Sorry,Anthony, those are 'brine shrimp' nauplei, not Daphnia. I hope this means you are maintaing a culture of Hydra on an ongoing basis? charlie guevara, NJ,US

Well my humor sincerely conveys admiration for those Pelmatohydra oligactis images (?with Daphnia pulex sp?). Thanks ...
