The Red List of Spiders from 2016 lists 992 taxa for the German spider fauna, excluding not yet established species. Together with recently newly recorded species 1013 species and subspecies are known from the country (araneae Version 09.2020) - about 2 % of the world spider fauna and 21 % of the European spider fauna.

In Germany the study of the spider fauna has a long tradition. Today arachnologists are networking worldwide. Several online-services are available: information portals (e.g. AraGes), checklists, record and literature databases (e.g. Atlas of the European Arachnids), the World Spider Catalog und the internet identification portal araneae Spiders of Europe, the German Forum and Wiki are building a Virtual Research Environment Arachnology.

The Arachnologische Gesellschaft (AraGes) aims at increasing and distributing the knowledge about arachnids. Focussing on the arachnid fauna of Central Europe, it also supports arachnological research in this region. Its foremost activities are: the publication of the scientific journal Arachnologische Mitteilungen / Arachnology Letters, the organization of meetings, the networking and exchange of information. The AraGes is a scientific institution incorporating a bridging function between interested amateurs, state authorities and academic research.

Natural History Museums

in Germany holding arachnological data collections, e.g.  Staatliches Museum für Naturkunde Karlsruhe (SMNK) and Staatliches Museum für Naturkunde Stuttgart (SMNS) are nodes of a European Arachnological Network. They mobilise their ecological data on spiders through this portal, ensuring as public institutions with their infrastructure and know-how permanent keeping and management of valuable data for research.
