| Research Abstract |
Based on critical examination on newly collected and voucher materials, 35 taxa belonging to five families of oligochaetes (Annelida, Clitellata) were recorded from profundal bottoms of 50 freshwater lakes in Japanese archipelago. The profundal communities in oligotrophic lakes were consisted of diverse species in variable families, which could be adapted to oligotrophic and ever-cool environments, and derived from underground or phreatic waters in the watershed. On the other hand, oligochaete communities in eutrophic lakes were dominated by a small number of tubificine species. It is suggested that species composition of profundal oligochaetes can be related to zoogeographical location of the lakes as well as trophic state of lake waters.
