Welcome to Systema Naturae, the interactive portal where you can explore the diverse branches of the eukaryotic tree of life (organisms whose cells possess a nucleus). Feel free to scroll through the phyla, classes, orders and families of plants, animals, fungi and various single-celled organisms. The idea for this project arose from the various observations that the author made in the natural environment, especially since 2017. It conveniently displays most of the organisms that he observed on countless trips and will be expanded continously to include new observations. Here, the classification follows a hierarchic system, which in many cases does not portray the relations between groups of organisms well, but is used for simplicity. It certainly is able to present a good overview of the various evolutionary groups.

5 kingdoms, 1421 species
