The most familiar representative of the glass sponges is the Venus' flower-basket. A number of animals use these sponges for shelter and protection including shrimp. A male and female shrimp pair will take up residence in the flower-basket house when they are young and continue to grow until they are too large to leave the confines of the sponge. When the couple reproduces young, the offspring are small enough to leave the sponge and find a new Venus' flower-basket. The relationship between the shrimp and the sponge is one of mutualism as both receive benefits. In return for protection and food provided by the sponge, the shrimp help to keep the sponge clean by removing debris from the sponge's body.
