Eastonia rugosa from Sardinia

What is it about?

We report the first record of Eastonia rugosa in Sardinia. Living individuals and loose valves were found in proximity of the Rio Padrongianus delta. Several alien species were found in the same area. It cannot be excluded that E. rugosa reached this locality by anthropogenic media. This issue is very important to understand to what extent E. rugosa is adequate as a descriptor of the Mediterranean Sea ‘tropicalization’ as suggested in recent monitoring programmes.
