Description
The Swedish Red List is produced by the Swedish Species Information Centre at SLU. The evaluations were made in collaboration with more than 100 experts, subdivided into 14 committees treating different organism groups. The Swedish Red List 2020, published on April 22 2020, is the fifth Swedish Red List based on the international IUCN criteria. The end product is two-fold, the actual redlist with species assessments and an analysis report. They are available both in printed editions and digitally. Further reading, species-specific information and analysis of results are available at www.artdatabanken.se.

Volvulella versus Rhizorus: Unfortunately many shelled opisthobranchs have been named on the basis of their shells alone, and this is a case in point. For the last 100 years there has been an on-going debate, unhappily still unresolved, over the names Volvulella Newton, 1891 [type species Bulla acuminata Bruguiere, 1792] and Rhizorus Montfort, 1810 [type species R. adelaidis Montfort, 1810] and whether they are synonyms. The shells certainly look the same but as they were described only on the shell it is very difficult. On top of that, Mediterranean and North American workers seem to prefer Volvulella while workers on the European North Atlantic and Australian - New Zealand regions have opted for Rhizorus.(note posted June 30, 2008 by W.B. Rudman in the Sea Slug Forum, Australian Museum, Sydney)
