The Yellow Tube Sponge is also known as Aplysina fistularis. Just like most other sponges, the Yellow Tube Sponge can reproduce by fertilizing eggs and by pieces of the sponge falling off and moving to other locations. Sperm and eggs are released by the sponge and the eggs become fertilized. The fertilized eggs drift in the water until they reach a hard surface, where they begin to grow. Another way this species can reproduce is by a piece of the sponge falling off and moving to a new location by the water current. At the new location, the sponge begins to grow as an adult sponge.
This picture shows how a Yellow tube Sponge can live in various places such a reef or on the ocean floor, which is shown in the picture at the top of the page.
