Sponges

Hi my name is Reed. Did you know that the simplest invertebrate is the sponge. These sponges are in the ocean that in your house they don't clean. Sponge are likely to be on rocks and on the ocean floor, they don't move around at all for some reason. They can mould into any shape. Their bodies have holes or I call them pores that carry water throughout the top of the sponges. If a sponge loses a body part it can regrow it. That is called regeneration. It's weird because they can regrow any body part. Well that's my story. Later
