This database contains specimens of invertebrates from the Gothenburg natural history museum, collected from the early 1800´s to the present. New specimens are added continuously. The main bulk of the collection consists of ethanol-preserved specimens of marine benthic invertebrates (notably L.A. Jägerskiölds marine survey 1921-1938 and the Swedish Taxonomy Initiative´s marine survey 2004-2009), parasitic worms from the Swedish west coast (notably collections from Peter Olsson and Orvar Nybelin) and dry mollusc shells. However, there are both wet and dry preserved specimens of a wide array of taxa from the entire world.
