[email protected] Abstract: The pearl oyster Pinctada radiata (Leach, 1814) is an alien species introduced to the Mediterranean Sea and recorded in Tunisia many years ago. However, since its record in Tunisian inshore areas, no studies have been carried out about the spread of this invasive mollusc. Thus, the status of this species is still poorly known and there is a knowledge- gap about its distribution and ecology.
