sponges in the ocean

Hi I am going to talk to you about sponges.The sponges I am going to talk about are real live sponges.They are usually found on rocks or other things on the ocean floor.They don't move around because their bodies don't have definite shapes.Sponges have holes or pores and the holes or pores carry water throughout their bodies.Water comes in at the pore and comes out of the top of the sponge.The water contains food and oxygen for the cells.The weird thing is if something gets cut off it will grow back.It is called regeneration.Animals that have simple body parts can regenerate.Sponges sound cool and I wish I lived close to an ocean!!!!!!!!That's all and GOODBYE!!!!!!
