- V-Marked Lucina
The species is easily identified by the curious sculpture of numerous oblique undulating lines (striae) crossing shell surface and changing direction along a line in the anterior third of shell. Concentric ridges and striae may be observed beneath the divaricating lines. Shells are rounded, inflated and white. Traces of a brown external coating (periostracum), more evident near margins. Shell up to 4 cm across.
Members of this family group have bacteria, usually in the gills, which can fix carbon dioxide and contribute to sulphide oxidising symbiosis. The feeding appendages and alimentary tract are reduced in size and complexity. Studies of a Californian species living in a sewage outfall, revealed metal sequestering granules in the gills, enabling it to detoxify metal pollutants. Haemoglobin is found in some species and is probably associated with the sulphide oxidising symbiosis.
In moderately exposed sand, to depth of 14 m.
Most states of Australia.
