Annelid invaders in the Black Sea region: The distribution of Streblospio gynobranchiata and first occurrence of Laonome xeprovala

The present study reports the spread of Streblospio gynobranchiata (Annelida, Spionidae) off Romanian coast and adjacent waters and the first occurrence of Laonome xeprovala (Annelida, Sabellidae) in the Black Sea basin. The spionid is considered among worst invaders in Mediterranean soft bottoms, w...
