Microlife: Thumbnails by shape

The following is a quick review of the organisms shown on the other pages here, with the same images linked to the descriptions, but arranged by general form instead of phylogeny. The hope is that another amateur can easily recognize if something they found is listed. I’d be interested to hear any thoughts on how well it works!
