title: &lt;i&gt;POLYDORA WEBSTERI&lt;/i&gt; - A COMMENSAL OF &lt;i&gt;ANADARA KAGOSHIMENSIS&lt;/i&gt; IN THE AZOV-BLACK SEA REGION
abstract: In January 2020, the presence of polychaete borers in the invader clam Anadara kagoshimensis (Tokunaga, 1906) was noted at the Chushka spit near Port Kavkas. Morphological analysis showed that the polychaetes belong to the species Polydora websteri Hartman in Loosanoff &amp; Engle, 1943, non-indigenous to the Azov-Black Sea basin. This species was first recorded in coastal waters of Romania on carbonate rocks in 1997, followed by findings in 2009 and 2019 in coastal areas of Sevastopol and Lake
