The focus of this resource is on Australian freshwater molluscs an extraordinarily diverse group of animals found in in a wide range of natural and man-made habitats, including rivers, streams, lakes, billabongs, ponds, dams, irrigation channels, and desert springs. They vary greatly in size, shape, and biology, with more than 99% of the native species occurring nowhere else.
These molluscs commonly play an important ecological role and, in some cases, are of economic, veterinary and medical significance. Non-native invasive species are also included in the key; species already present and those at risk of being introduced, given the biosecurity risks involved.
An unusual feature of this key is that users can select the context in which they use it; that is, they can choose a subset of the key (as shown – click/tap to enlarge) or use the full key of over 530 taxa.
