Arachnology is the science of arachnids, a class of arthropods with about 100.000 described species worldwide and certainly many more undescribed species.

Arachnologists study many aspects of the biology of arachnids. They are well organized and cross-linked. There is an International Society of Arachnology, a European Society of Arachnology and several national and regional Organisations.

The Arachnologische Gesellschaft tries to fulfill a bridging function between interested amateurs, state authorities and academic research in the field of arachnids, mainly in the German language area. To do so we offer contact and links to further authorities and data sources (the Atlas, collection portals). In the future we will offer access to literature and ecological databases and collections.
