Australian Museum Malacology Collection - Marine records

OBIS Australia Open in mapper Explore occurrences

Malacology is the study of the group of animals called molluscs. Molluscs include chitons, clams, mussels, snails, nudibranchs (sea slugs), tusk shells, octopus and squid. The Australian Museum Malacology collection is one of the world's largest of its kind, covering all groups of recent (up to 1.6 million year old) and tertiary (65-1.6 million year old) molluscs. Many of the specimens are dry shells, but there is also a large collection of preserved molluscs. The collections date from the 1860s and include marine, terrestrial and freshwater molluscs. They are predominantly from Australia and the south-west Pacific, but also include specimens from other parts of the world. The Malacology type collection is extensive and includes a large number of primary types (types are the original specimens on which the first description of a particular species or subspecies is based). The collection was established in 1860 and continues to the present.
