| Summary: | Bivalvia is a class of freshwater and marine mollusks such as scallops, clams, oysters, or mussels which are bilaterally compressed and enclosed in a shell consisting of two hinged parts. The current qualitative study was designed to assess the biodiversity of Bivalvia in selected habitats at Helgoland, an island in the south-eastern part of the North Sea. Samples were collected by hand in the north-eastern intertidal rocky shore as well as by dredging in the “Tiefe Rinne”, an area south of Helgoland 50 to 60 m deep. The number of species identified was 14. Nine species were collected in the intertidal rocky shore Cochlodesma praetenue, Dosinia exoleta, Dosinia lupinus, Mya arenaria, Mytilus edulis, Parvicardium scabrum, Polititapes aureus, Timoclea ovata and Venerupis corrugata. Whilst the dredged species were Modiolus modiolus, Aequipecten opercularis, Mimachlamys varia and Ostrea edulis. Magallana gigas was only observed by chance in the south harbor and Mytilus edulis was found underneath a pontoon in ... |
