On the occurrence of Pinctada radiata (Mollusca: Bivalvia: Pteriidae), an alien species in Croatian waters

Two specimens of lessepsian bivalve Pinctada radiata were encountered in a benthic study conducted at a depth of 59 m on a silty-sand bottom in the northern Adriatic Sea, Croatia, in April 2006. This is the first record of the species in the Croatian part of Adriatic Sea.
