Porifera: ReproductionAsexual

After fragmentation (Parts of the sponge fall off and start to grow elsewhere)

By producing gemmules (releases them when dying, go dormant and start to grow when the environment is right)

By budding (new organism grows on another)

Sexual (Main)Sponge releases spermTravel to another sponge

and fertilize the eggs there

Porifera: HabitatSpans the entire

globeQuiet, clear watersMore abundant in

temperate waters
