Description :
The present study deals with the observations on germination of gemmules of a freshwater sponge Trochospongilla. The gemmules were collected from freshwater pools at the Sagareshwar sanctuary Dist. Sangli, Maharashtra. The production of gemmules is a trait shared by freshwater sponges but the gemmules display different levels of complexity. The functional role of gemmules is double as propagules and as resting bodies. They are efficient means of dispersal. The low metabolism of gemmules allows sponges to survive extreme environmental conditions. The temperature and pH are key factors in germination of gemmules in Trochospongilla.
