What are the special traits of a sponge?
Sponges are very interesting organisms. They are made of either spiny filaments called spicules or spongin, which is soft. To eat, they pull in water from around them and take out the nutrients, then send the water back out. That's why they have so many holes and why people use them for cleaning; they hold so much water. They don't have any organs, so the nutrients are carried to different parts of the body by amebocites, which are special cells that travel all around the sponge's body, depositing nutrients where they are needed.
Do sponges have one opening?
No in fact they have multiple openings called pores, which allow water and nutrients to flow in and out of the sponge
