An Illustrated Checklist of Freshwater Microscopic Life replaces A Beginner's Guide to Freshwater Microscopic Life by artist and microscopist David Seamer. The book is filled with hundreds of line drawings by the author from live microscopic observations. The guide contains helpful taxonomic information and detailed descriptions. Notably, each of the hundreds of organisms featured here (including common pond microscopic organisms such as amoeba, ciliophora, flagellates, heliozoans, tardigrades, and algae) has a worldwide distribution, and many can be found in the UK. The guide is spiral-bound for ease of use while working at the microscope.
