Abstract
By successively filtering off animals emerging from mud cores taken to the laboratory, the degree of torpidity within the same species was found to vary considerably both time and space. Variation in time from the start of dormancy follows a pattern of diapause development similar to that of insect diapause. In some localities dormancy is deep and prolonged, while in others it is less pronounced and lasts for a shorter period. The depth of torpidity during winter seems to be correlated to an induction early in the year. The intensity of diapause varies along the slope of the localities and down into the bottom mud. In some cases high temperatures seem to induce a deeper torpidity.
