All sponges possess a remarkable ability to regenerate lost parts. A piece cut from the body of a sponge is capable of growing into a complete sponge. This power of regeneration helps the sponges to repair the damage caused in the harsh environment.
Next to sexual reproduction, there are several other and more common ways of asexual reproduction like budding and branching, fission and fragmentation and the release of gemmules.
The sponge shown below was recovered from the Isola di Mozia lagoon in the neighborhood of Marsala on the island of Sicily.
