Full Answer

Although a sponge can't do much to increase its lifespan, it can reproduce to create offspring to carry on genes. Sponges reproduce by budding. Sperm is released and catches on other sponges where it is fertilized internally. The larvae is then released and settles on the ocean floor when it continues to grow into a sponge.

As a form of self-preservation, sponges have the ability to regenerate lost pieces broken off by strong water currents. Divers who harvest sponges always leave the roots of the sponge in place so a new animal can grow.
