Detail
S. nucleus was described by Studer 1820, who placed it in the genus Cyclas. It was later thought to be a sub-species of Sphaerium corneum. Subsequently it was raised to a full species again as Sphaerium nucleus (Studer, 1820) due to its having a different form of kidney, and the shell having a broad hinge plate, dense porosity and more tumid shells with broad umbones. Unlike S. corneum it has a preference for temporary habitats. Distribution: Europe, Central Asia. Austria, Britain and Ireland, Czech Republic - in Bohemia, in Moravia, Germany, Kyrgyzstan, Slovakia, Ukraine. This species lives in freshwater, in periodic standing water.
