Beskrivelse af Invertebratsamlingerne
During the past two centruries, the Second (= Invertebrate) Department has primarily paid attention to the study of marine invertebrates. This is mainly due to the history of the Danish Kingdom, its navy, its overseas trading activity and its past interest in colonies. The collections go back to pre-Linnean times. Geographically, the collections are strong in areas around The Faroes, Iceland, Greenland, the West Indies, and of course for Danish waters. Many expeditions have supplied material, both from the deep sea, open sea and shallow waters, e.g., shipborn expeditions such as the Galathea, Dana, Ingolf, Godthåb, or led by prominent scientists such as Forsskål, Th. Mortensen, C.G.Joh. Petersen, and G. Thorson.
The most important parts of the collections are the type collections, and its cataloguing is still going on. The collection holds many types from the late 18th century and early 19th century. At that time specimens were traded, sold at auctions, exchanged and even looted. Many of these are types, and in order to reduce the amount of nomenclatorial and taxonomical confusion the old collections are still searched for valid types, which also demands the University's good old library. The following gives a survey of the individual systematic parts of the collection.
Platyhelminthes, Aschelminthes, og Proarthropods
Smaller groups: Entoprocta = Bryozoa, Phoronida, Brachiopoda,
