abstract: "<p><em>Hematodinium</em> is a parasitic dinoflagellate with a wide distribution along the European coastline. We investigated whether <em>Hematodinium</em> occurs in the Wadden Sea, a large tidal flat system spanning the Netherlands, Germany and Denmark, where to date no records exist. In total, we investigated eight different species from six sites at the southern (Texel, Netherlands) and northern ends (Sylt, Germany) of the system. Based on microscopic hemolymph screening, we did not detect <em>Hematodinium</em> in any of the 1252 investigated individuals. An extensive additional literature review revealed 1489 <em>Hematodinium</em> records in Europe from 14 crustacean species, most locally occurring at high prevalence. This makes our finding of lack of <em>Hematodinium</em> infections surprising and suggests that environmental factors such as a lower salinity may limit the distribution of <em>Hematodimium</em> at the investigated locations at both ends of the Wadden Sea. However, whether the entire Wadden Sea represents a distributional gap for <em>Hematodinium</em> remains to be investigated.</p>"
