INTRODUCTION This review aims to summarize currently available knowledge of target species at six Natura 2000 sites in the Adriatic Sea that were selected as case studies within the project ECOSS. The sites included are: Trezze San Pietro e Bardelli (IT3330009), Delta del Po (IT3270017 and IT3270023; two sites geographically overlapping and thus here combined), Tegnùe di Chioggia (IT3250047), Cres-Lošinj (HR3000161), Vis (HR3000469) and Malostonski Bay (HR4000015). For most of the Natura 2000 sites, the review is given for species
