OBIS Australia Open in mapper Explore occurrences

The Museum and Art Gallery of the Northern Territory (MAGNT) Malacology (mollusc) collection comprises about 57,000 lots of dry shells for scientific research and education purposes, and about 2,000 specimen lots stored in either 70% ethyl alcohol for morphological study or absolute ethyl alcohol for genetics studies. The bulk of the collection is registered into a database. Marine, land and freshwater species of molluscs are represented in the collection, with substantial holdings of shallow water tropical species from the Indo-Pacific, South East Asia and Northern Australia, with smaller holdings from other locations. Data downloaded from ALA (http://collections.ala.org.au/public/show/co141) and taxa matched to the World Register of Marine Species. This dataset excludes non-marine taxa.
