| Abstract |
The pleustid amphipod Incisocalliope aestuarius (Watling and Maurer, 1973) was described from the North American Atlantic coast in the 1970s. In this study, the species is reported from the German North Sea for the first time. An established population was found in four different harbour locations along the coast of Lower Saxony for five consecutive years since 2016. In Europe, I. aestuarius has already been reported from France, the Netherlands and Belgium. As a member of fouling communities, the species tolerates reduced salinities and is often associated with hydroids growing on artificial hard substrates. Due to its cryptic lifestyle, as well as its challenging identification, the species has been overlooked for years. Therefore, it seems likely that I. aestuarius has already been established in more estuarine or harbour locations in Europe. |
