Sponges may reproduce sexually and asexually. Most sponges are hermaphrodites, both male and female. In sexual reproduction, the male sponge releases sperm into the water, which travels in the current and then enters a female sponge. After fertilization in the sponge, a larva is released into the water. It floats around for a few days and then sticks to a solid surface to begin its growth into an adult sponge. Sponges are also able to reproduce asexually through budding. A small piece of sponge breaks off and grows into another sponge with DNA identical to the parent sponge.
