Best Answer: Sponges may reproduce sexually and asexually. This helps keep them alive in their habitats. Most sponges are both male and female. In sexual reproduction, they may play either role. The âmaleâ sponge would release sperm into the water, which would travel and then enter a âfemaleâ 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 to begin its growth into an adult sponge. Sponges are also able to reproduce asexually through budding. This is when a small piece of sponge is broken off but is still able to survive and grow into another sponge. Sponges are also able to repair damages to their bodies. These characteristics of sponges are ideal because even small parts of sponges may survive in the water.
