Molluscs of southern Africa's Journal

There are not many popular references for snails in southern Africa.
The two most exciting terrestrial ones are:

• DG Herbert 2010 The introduced terrestrial Mollusca of South Africa. SANBI Biodiversity Series 15
• D Herbert & D Kilburn 2004 Field guide to the land snails and slugs of eastern South Africa. Natal Museum Pietermaritzburg

sadly there is nothing for the western half of the subcontinent, or for tropical southern Africa.

There are many marine guides - what are your favourites?

Molluscs are a diverse group. Rather than create lots of projects, why not use these links to look at groups of molluscs if your interests are more specific.
These are set to show the species: use the menu bar to select observations, identifiers or users, or adjust the filters or regions (country, province, magisterial district) or genus or species..
