New data on Aplidium tabarquense (Tunicata: Ascidiacea) distribution in the Adriatic Sea

The colonial ascidian Aplidium tabarquense Ramos-Esplá 1991 was recorded in Montenegro during a monitory survey carried out by scuba divers on an underwater outfall of the wastewater discharge system in TraÅ¡te Bay. Several colonies were present on artificial substrata at a depth of 27 m. This is the first record of the species in the South Adriatic Sea. Further observations are recommended both to delineate the effective distribution and population density of A. tabarquense in the Mediterranean Sea and to widen the knowledge on ascidian diversity along Montenegroâs coasts
