Gemmule is produced by few genus of freshwater sponges such as Spongilla and some marine species including ficulina ficus, sea sponges, and other poriferans, which produces gemmules to survive in the unfavourable conditions and to germinate and produce new sponges.
How are gemmules produced?
In zoology, gemmules are produced by sponges which can be dormant through the winter, and then later develop into new sponge.

Why do some sponges form gemmules?
When conditions deteriorate, such as when temperatures drop, many freshwater species and a few marine ones produce gemmules: “survival pods” of unspecialized cells that remain dormant until conditions improve. They then either form completely new sponges or recolonize the skeletons of their parents.
