Scoloplos armiger is a widely spread species that was only found scarcely in the eastern coastal zone (1994-2001 period). In the same period the species was mainly distributed near the western coastal zone, the Flemish and Zeeland Banks, where the species reached a very high distribution frequency. The distribution frequency on the Zeeland Banks was remarkably lower. High densities were recorded in both periods: up to 5,000 ind./m2 (1994-2001 period).
