   Gemmule
   `Gemmules` are internal buds found in freshwater sponges and are the result of asexual reproduction, and resemble round, food-filled balls. Gemmules have a protective coat composed of spicules and organic matter. They are resistant to desiccation (drying out), freezing, and anoxia (lack of oxygen) and can lie around for long periods of time. When conditions improve, gemmules give rise to an adult Sponge.
