This is a collection of photos I have taken of microscopic life, including protozoa, algae, and animals, from several millimetres down to around 20 µm in size. They are generally more common types, but each habitat has its own characteristic flora and fauna, and even these are often impressively diverse.
I’ve arranged these into a rough guide, which hopefully might be of use in recognizing your own finds, or explaining a little about what is out there. Note, though, that this is very far from a complete list, and though I have done my best, I am not a biologist and may well have made some mistakes.
This site is updated seasonally to annually as time permits. Please enjoy, and feel welcome to contact me if you have questions, comments, or requests. Also, if you’d like to help out, I’d appreciate your sparing a glance at my most wanted identifications.
Thanks, Joshua Grosse
