A survey of the marine bivalves and gastropods of Shelly Beach, Port Macquarie, on the north coast of New South Wales, Australia

摘要

The New South Wales (NSW) north coast has a diverse marine bivalve and gastropod fauna ofbiogeographical interest. A field survey at Shelly Beach, on the NSW lower north coast over the period 2009-2015, complemented by a review of data from secondary sources, identified 142 species comprising 34 bivalves (24 families) and 108 gastropods (51 families). It is likely that further survey effort, particularly targeting micro-molluscs less than 5 mm in size, would identify additional species. The molluscan fauna of Shelly Beach reflects the location of the NSW north coast in an overlap zone between the tropical Indo-West Pacific region to the north and the temperate southern Australian region to the south. Temperate zone species comprised about 63% of the identified species diversity, sub-tropical species about 20%, overlap zone endemics about 12% and widespread species about 5%.
