No in fact they have multiple openings called pores, which allow water and nutrients to flow in and out of the sponge
osculum - a large opening in a sponge through which water flows out of the sponge. Sponges may have more than one oscula.
A digestive system with only one opening is called an incomplete digestive tract. Organisms with this type of digestive system ingest food and eject waste through their mouth.
The Porifera are the sea sponges. Some simple examples are the kitchen or bath sponges or other sponges that one can see diving -- from barrel to branch sponges.

normal sponges (car sponges, etc.) are yellow. green is the colour for dishwashing sponges, and spongebob does NOT clean plates. although, there is one time where he actually did.

No, barrel sponges do not migrate. They are sessile organisms, meaning they are permanently attached to a surface and do not move from one place to another. Barrel sponges rely on water currents to bring them food and oxygen.
There are many types of sponges you can use for cleaning. Examples of these are cellulose sponges, abrasive sponges, natural sponges, and dry sponges. The best one would depend on the cleaning surface. It is best to use soft sponges such as the natural sponge to clean fragile surfaces. To clean rough surfaces an abrasive sponge would do the trick.

Yes they do :)
they r sexual...because the reproductive organs in the male and female sponges differ from one another
