Here is an overview of the systematic groups of the freshwater organisms that have been found so far. Many animals whose larvae live mainly in the water eg. dragonflies etc. are living outside of the water when adult. These creatures are listed as well as those plants which occur at the littoral zone.
The classification for microscopic organisms is mainly based on the German book "Das Leben im Wassertropfen", although the classification given there is not by all means "state of the art". Further literature which is consulted is listed here.
At the moment this website is being translated from German to English. This will take some time. So I beg your pardon for any inconvenience. The German pages of this site are no longer supported or maintained.
