Stat"oblast (), n.[Gr. standing (i. e., remaining) + -blast.] (Zol.) One of a peculiar kind of internal buds, or germs, produced in the interior of certain Bryozoa and sponges, especially in the fresh-water species; -- also called winter buds. They are protected by a firm covering, and are usually destined to perpetuate the species during the winter season. They burst open and develop in the spring. In some fresh-water sponges they serve to preserve the species during the dry season. See Illust. under Phylactolmata.
